Democrats and Republicans have split sharply over President Donald Trump’s decision to carry out strikes in Venezuela that resulted in the capture of President Nicolás Maduro and his wife, with a growing number of Democratic lawmakers calling the operation unconstitutional and some openly urging impeachment.

Progressive Democrats have led the backlash, accusing the administration of launching an illegal military action without congressional authorization. Several lawmakers argue that the operation amounts to an invasion of a sovereign nation and violates both the Constitution and the War Powers Act.

“Many Americans woke up to a sick sense of déjà vu,” Rep. Delia Ramirez (D-Ill.) a member of the House’s progressive “Squad,” wrote on X over the weekend. “Under the guise of liberty, an administration of warmongers has lied to justify an invasion and is dragging us into an illegal, endless war so they can extract resources and expand their wealth.”

Ramirez called for Congress to pass a War Powers Resolution introduced by Rep. Ilhan Omar, D-Minn., aimed at blocking further military action against Venezuela, and said Trump “must be impeached.”

Omar’s resolution seeks to reassert Congress’ constitutional authority over war-making and would require the administration to halt hostilities unless lawmakers explicitly approve them.

Rep. Dan Goldman (D-N.Y.) echoed those concerns, criticizing Trump for bypassing Congress to launch what he described as a war with Venezuela. Goldman said the administration failed to provide lawmakers with “any satisfactory explanation” for the strikes.

“This violation of the United States Constitution is an impeachable offense,” Goldman said in a statement. “I urge my Republican colleagues in the House of Representatives to finally join Democrats in reasserting congressional authority by holding this president accountable.”

Other Democrats struck a more cautious tone. Rep. April McClain Delaney (D-Md.) stopped short of naming Trump but wrote on X that “invading and running another country without a congressional declaration of war is an impeachable offense,” while also questioning whether impeachment is the most effective strategy. “Whether it makes sense to pursue impeachment as the best strategy to end this lawlessness is a tactical judgment that our Caucus needs to seriously deliberate,” she wrote.

In California, Rep. Eric Swalwell (D-Calif.) a gubernatorial hopeful, said he would not rule out supporting impeachment when asked by reporters, according to the Pleasanton Weekly.

Progressive candidates running for office also weighed in. Kat Abughazaleh, a Democrat seeking an open House seat in Illinois, called Trump a “war criminal” in a post on Bluesky and demanded Congress “halt this conflict and impeach” the president.

Still, Democrats are not unified in their opposition. A number of more centrist lawmakers have either defended the administration’s actions or argued that the removal of Maduro serves U.S. national security interests. Some Democrats have described the operation as a targeted effort to remove a destabilizing authoritarian leader rather than the start of a broader war, while others have said the administration should now work with Congress to define limits and next steps.

Republicans, for their part, have largely rallied behind Trump. GOP leaders characterized the operation as a decisive blow against a longtime adversary of the United States and a win for regional stability.

Senior Republicans have also pushed back on claims that the administration violated the Constitution, arguing that the action was a limited law enforcement or counterterrorism operation rather than a traditional military engagement requiring prior congressional approval.

While impeachment calls are growing among progressives, Democratic leadership has so far stopped short of endorsing that approach
