Did President Trump need Congress to approve going in and getting the President of Venezuela?

1. The constitutional baseline: Congress declares war, but presidents conduct wars

Article I gives Congress the formal power to declare war, a point echoed across reporting and political statements after the Venezuela operation, and the War Powers Resolution of 1973 was written to limit unilateral presidential military action by requiring consultation and, in many cases, congressional authorization for the introduction of U.S. forces into hostilities ^{[1] [2] [3]}.

2. The War Powers Resolution’s mechanics and the 48‑hour rule

Under the War Powers Resolution, presidents must notify Congress within 48 hours of introducing U.S. forces into hostilities and are constrained from sustaining hostilities beyond 60–90 days without congressional authorization; reporting notes the administration’s legal posture was not publicly articulated at the time of the raid and that the White House had not sought explicit prior approval from Congress ^{[2] [3]}.

3. The administration’s likely legal rationales — Article II and law‑enforcement claims

Administration officials and some Republican senators have argued that a president has inherent Article II authority to use force to protect U.S. national security or to execute criminal indictments of foreign leaders, and outlets reported that Trump earlier said he did not believe prior congressional approval was required for strikes in Venezuela ^{[3] [2]}; the administration also pointed to criminal indictments of Nicolás Maduro as underpinning a domestic-law justification for the operation, a point observers flagged as central to the White House narrative ^[5].

4. Congressional reaction and political constraints, not just legal ones

Lawmakers from both parties demanded briefings and suggested the operation lacked congressional consent, with Senate leaders preparing a war powers resolution to block further actions without explicit approval — reactions that underscore the political, as well as legal, cost of bypassing Congress even when the executive asserts authority ^{[1] [6] [7]}.

5. Legal debate: narrow raid vs. sustained hostilities

Scholars and commentators split on whether a targeted extraction can be treated as a limited law-enforcement action exempt from the War Powers Resolution or whether it constitutes hostilities requiring congressional authorization; some legal experts in the press and opinion pages characterized the operation as illegal under both U.S. and international law, while administration allies urged that the action falls within presidential powers — a disagreement that is factual and normative and remains unresolved in the sources ^{[4] [5] [2]}.

6. What reporting shows and what it does not — limits of public record

Contemporary reporting documents that Congress was not informed in advance and that many Democrats (and some Republicans) say the president did not seek approval, but the public record in these sources does not include a detailed, published legal memorandum from the administration explaining which statutory or constitutional authority it relied on for the raid — that absence is pivotal to assessing whether Trump “needed” Congress in legal terms versus political prudence ^{[3] [7] [2]}.

7. Bottom line: legal ambiguity, political peril

Legally, presidents can and have used asserted inherent authority to order limited strikes or arrests abroad without prior congressional authorization, but such uses are contested and often trigger congressional checks like resolutions or litigation; politically and practically, the consensus in the coverage is that the administration should have sought congressional buy‑in for an operation of this magnitude even if it believed it had legal authority — and Congress is moving to assert its role ^{[3] [1] [7] [4]}.
