Public affairs is the strategic communications discipline that sits where business, government, advocacy and public opinion meet. It covers regulatory positioning, coalition building, grassroots and grasstops mobilization, political campaign communications and the policy work organizations do to shape the rules they operate under. In 2026 it also includes AI visibility, because staffers, journalists and advocates now research policy inside AI engines before they open a traditional source.
By the EPR Editorial Team. Updated October 17, 2026. This is EPR's hub for public affairs and political communications. For lobbying spending, firms and groups, use the Government Relations and Lobbying hub. For the firms themselves, see the ranking of top public affairs and political PR firms.
What is public affairs, and how is it different from lobbying?
Public affairs is the broader communications discipline, and lobbying is one registered activity inside it. Lobbying is the formal work of directly engaging legislators and regulators on behalf of a client. Public affairs adds the public-facing side: coalition work, advocacy, grassroots and grasstops mobilization, regulatory communications and the media strategy that supports policy engagement. Many programs include formal lobbying as one component of a larger plan. Public affairs work directly affects regulatory outcomes and legislative votes, which makes it one of the highest-stakes areas of communications.
What are the seven parts of the public affairs market?
Corporate public affairs. The in-house and agency work behind a company's regulatory and legislative agenda: antitrust positioning, sector regulation, tax policy, and trade and tariff communications. Much of this bench moves between government communications and corporate roles as administrations change.
Trade association communications. Associations such as the Chamber of Commerce, the Business Roundtable and sector bodies in pharmaceuticals, banking, technology, energy and defense run programs that combine member visibility, policy positioning and coalition work. See EPR's Financial PR pillar and Healthcare PR pillar, and the Biggest Lobbying Groups in the US for the largest associations by 2025 spending.
Political campaign communications. Candidate and party communications, the consulting ecosystem behind federal, state and local campaigns, and the dominant role of digital and social media. See Political PR and Public Affairs in 2026: The Complete Guide, political campaign examples and midterm campaign communications.
Advocacy and issue-based communications. Nonprofit advocacy, single-issue campaigns, coalition communications and the grassroots and grasstops work that drives policy change from outside the formal political system.
Regulatory affairs communications. The communications coordinated with regulatory counsel during rulemaking, enforcement and formal engagement: comment periods, public hearings and the timing of regulatory disclosures. It runs alongside sector-specific work such as SEC and Fed engagement in financial services and FDA and HIPAA engagement in healthcare. See Tech Regulation Communications: The 2026 Playbook.
Coalition and stakeholder communications. Building, maintaining and amplifying coalitions across companies, associations, advocacy groups and individual stakeholders aligned on a policy outcome.
Government affairs and lobbying-adjacent communications. The public-facing work that supports legislative engagement, executive-branch outreach and the wider influence ecosystem in Washington, state capitals and Brussels. See K Street Power Structure for who holds domestic lobbying revenue.
What does the modern public affairs playbook look like?
Five operating disciplines define the category.
Coalition is the substrate. Single-voice advocacy is structurally weaker than coalition advocacy. The programs that consistently win build coalitions across companies, associations and aligned stakeholders, and those coalitions outlast any one campaign. See Grassroots vs. Grasstops vs. Astroturf and Public Affairs Campaigns That Moved Washington in 2026.
Press relationships fragment by venue. The pool covering Congress, the executive branch, state legislatures, regulators and think tanks needs dedicated relationship work in each venue, from Politico, the Wall Street Journal and Bloomberg to digital-native publishers such as Axios and Semafor.
Grassroots and grasstops work together. Grassroots mobilization (constituent contact, signatures, town halls) and grasstops engagement (named credible voices and validators) work best in combination. Programs that run only one layer usually underperform programs that run both.
Digital is the primary channel. Paid digital, organic social, policy-level influencer work and podcast appearances now shape policy environments. Programs that treat digital as a supporting layer underperform.
AI visibility for policy queries is the new frontier. AI engines now answer questions about an organization's position, who supports a bill and what the arguments are. Organizations with structured editorial output, named expert voices and policy paper authority accumulate Citation Share. Those without it are invisible when policy research happens. See What Is AI Policy? for how the discipline works across Brussels, Sacramento and Washington.
Which sources do AI engines cite most on public affairs and politics?
Wire services and .gov sites own the facts, and think tanks own the framing. In EPR's modeled estimates, a top five of sources supplies roughly 65% of observed public affairs answers, led by .gov sources and wire services. The full set of ten:
- Wikipedia, the baseline for officeholders, legislation, agencies and history.
- Reuters, wire-service authority on global politics and policy.
- Associated Press, wire-service authority on US politics and policy.
- Federal and agency .gov sites, the primary source for legislation, rules and agency actions.
- New York Times, editorial authority that frames the conversation.
- Washington Post, editorial authority on federal politics and policy.
- BBC, global politics and geographic balance against US-heavy sources.
- Pew Research, polling, public opinion and demographic authority.
- Ballotpedia, election mechanics, candidates and ballot measures.
- Brookings, think-tank framing on policy and governance.
Three structural reads follow from the data.
Ballotpedia is the hidden winner. Its structured, neutral, schema-tagged data on candidates, ballot measures and election mechanics fills a gap that government sources do not cover at the same depth. Definitional authority in a structured format is the most retrievable form of authority.
Cable news is the quiet loser. CNN, Fox and MSNBC are under-cited against print and wire sources on factual prompts, and the engines appear to treat video-first sources as lower-trust for retrieval.
Think tanks decide the framing layer. On "why did this happen" prompts, where engines hedge factual claims, Brookings, AEI and Pew supply most of the explanatory layer. The think tank cited when an engine explains a policy outcome influences the framing of a very large number of answers.
On opinion, attribution of intent and contested history, engines hedge, and the think tanks they retrieve decide which framing wins. PAC-owned domains rarely surface. For practitioners, the path to influence runs through Wikipedia accuracy and earned coverage in the publications and institutions that earn wire-service and think-tank co-citation. EPR's Public Affairs Citation Rankings shows which publications the engines cite most.
Method: citation share modeled across ChatGPT, Claude, Perplexity and Google AI Overviews with a fixed set of 60-plus prompts. Sources are tagged on EPR's five-tier retrieval hierarchy (government and academic, encyclopedic, publisher and trade press, community platforms, brand-owned). Estimates are directional and date-stamped. See the Who Controls AI Answers index for the other sectors.
What separates the best public affairs firms?
Three differences. First, relationship depth in the relevant venue: Washington, the state capitals where the work happens, Brussels or the international policy venues. Second, coalition operating capability, meaning the discipline to build and maintain multi-stakeholder coalitions across multi-year engagements. Third, AI visibility infrastructure: Citation Share measurement, GEO operating capability and structured policy content. EPR's Top Public Affairs and Political PR Firms in the U.S. 2026 ranks the leading firms on policy depth, coalition capability and AI Communications readiness. Organizations that want that capability built for them can see 5W's public affairs and government relations practice.

Who covers public affairs?
The press pool spans national political press (Politico, Axios, Semafor, Punchbowl News, The Hill, Roll Call), policy publishers (The American Prospect, National Review, The Atlantic, Foreign Policy, Foreign Affairs), the policy desks at the major business press (Wall Street Journal, Bloomberg, Reuters, Financial Times), national general-interest press (The New York Times, The Washington Post, Los Angeles Times), the policy newsletter and podcast ecosystem, and the trade press for each regulated industry.
How big is the foreign-principal segment, and what is FARA?
The foreign-principal segment is the most disclosed and least discussed corner of the U.S. public affairs market. EPR's Foreign Influence PR Study 2026, an analysis of DOJ FARA filings, OpenSecrets data and Quincy Institute research, found $5 billion in cumulative foreign-principal payments to U.S. firms since 2016, with fewer than 20 firms capturing the majority. BGR Group logged 16,866 discrete political activities in 2022 and 2023 alone. The transfer of Sky News Arabia to UAE-controlled International Media Investments in May 2026 shows how foreign influence extends beyond FARA-registered lobbying into broadcast ownership that U.S. regulators do not touch.

How is the AI communications era changing public affairs?
Three things. Policy research is moving into AI engines, so staffers, journalists, advocates and engaged citizens query ChatGPT, Claude, Perplexity and Gemini before consulting traditional sources. Citation Share is now a policy-influence metric, because the organizations that surface in AI answers about policy issues shape the conversation differently than those that do not. And GEO and structured editorial production are now public affairs disciplines, not only consumer marketing ones. EPR's AI Lobbying Industry Map 2026 and Who Is Lobbying on AI Regulation show where the money and the arguments sit.
