How does the volume of lawsuits filed against the Trump administration compare to previous administrations (Obama, Bush)?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Legal filings against the Trump administration in 2025 number in the hundreds by multiple trackers — Bloomberg and The Fulcrum reported 328+ lawsuits by May 1, 2025 [1], other outlets and trackers list figures like 186 as of April 22, 2025 [2] and trackers such as Lawfare and AP document “hundreds” of challenges [3] [4]. Contemporary reporting and trackers portray litigation levels far higher than the early months of recent presidencies, which some outlets say saw “dozens” or fewer than 50 suits in comparable windows [2].
1. Lawsuits in 2025: a contested, rapidly rising tally
Multiple monitoring projects and news outlets have logged hundreds of suits against the Trump administration in 2025: Lawfare runs a litigation tracker focused on national-security and executive actions [3]; AP summarizes that “hundreds” of suits have been filed challenging executive orders and administrative moves [4]; The Fulcrum and Bloomberg noted more than 328 suits by May 1, 2025 [1], while other Fulcrum coverage put the tally at 186 as of April 22, 2025 [2]. These differences reflect rapidly evolving filings, differing inclusion criteria (e.g., counting individual district cases, multistate suits, or only high-profile challenges), and the difficulty of a single definitive count [3] [1] [2].
2. How reporters and trackers count — why numbers diverge
Trackers use varied methodologies: Lawfare’s tracker catalogs national-security and executive-action litigation specifically [3]; Ballotpedia highlights multistate suits and compiles cases where states sue en masse [5]; The Fulcrum and Bloomberg report broader tallies across executive orders and agency actions, producing larger aggregates [1] [2]. Differences in which kinds of cases — e.g., individual plaintiffs, state coalitions, or Court of International Trade tariff challenges — are included explain why one outlet reports 186 while another reports 328+ or even 530 later in the year [2] [1] [6].
3. Comparison to prior presidencies: available sources and caveats
Reporting that compares Trump’s litigation volume to prior presidents notes a sharp gap in the early months: The Fulcrum cites that during President Biden’s first 100 days there were fewer than 50 lawsuits and Obama faced around 30 in a similar period, framing 2025’s numbers as “significantly higher” [2]. The Fulcrum’s broader coverage and other outlets characterize the Trump administration’s 2025 pace as far above typical early-term counts [2] [6]. However, available sources do not provide a comprehensive, side‑by‑side, fully normalized dataset across administrations accounting for differences in what counts as a suit, the role of state coalitions, or the political and legal contexts of each presidency [3] [2].
4. Subject matter driving the surge in filings
Trackers and litigants say many suits challenge sweeping executive orders and agency directives: birthright-citizenship and immigration measures drew multistate litigation, including nationwide preliminary injunctions [5] [7]. Suits have also targeted funding pauses, grant freezes, tariff policies, and executive actions described in trackers and news reports [8] [9]. Lawfare and Just Security focus on national-security and executive-action challenges; NGOs such as Democracy Forward and LDF highlight APA and civil-rights challenges to agency rollbacks [3] [10] [7].
5. Outcomes, context and competing narratives
Some advocacy groups frame these numbers as evidence of unlawful or overreaching policymaking: Democracy Forward cites an Institute for Policy Integrity finding that the administration “failed nearly 93% of the time” in APA challenges they tracked [10]. Conversely, the administration and some supporters argue litigation is politically motivated pushback against policy changes; available sources document many injunctions and blocks but do not present a unified assessment of the administration’s legal success rate beyond selective figures [10] [3]. Lawfare and AP present litigation as an ongoing check on executive action, without adopting advocacy framings [3] [4].
6. What the numbers mean for governance and the courts
High volumes of litigation strain court dockets and can functionally delay or block policies; trackers show many preliminary injunctions and TROs across cases [3] [9]. The Fulcrum and other outlets interpret the flood of suits as part policy conflict and part strategic litigation by states, NGOs, and private parties seeking immediate relief from sweeping orders [1] [2]. Available sources do not measure long-run policy effects across all cases, so the ultimate governance impact remains subject to court adjudication and appeals [3] [1].
Conclusion — what readers should take away
Reporting across Lawfare, AP, Fulcrum and others converges on this: 2025 saw an unusually large and rapid wave of lawsuits targeting the Trump administration’s early actions, with counts ranging from the low hundreds to several hundred-plus depending on methodology [3] [4] [1] [2]. Comparisons to Obama and Biden in the early days of their terms show materially fewer suits in those windows, but differences in counting methods and political context mean no single definitive cross‑administration statistic is available in the cited coverage [2] [3].
