WASHINGTON — Senate Republicans voted to dismiss a war powers resolution Wednesday that would have limited President Donald Trump’s ability to conduct further attacks on Venezuela after two GOP senators reversed course on supporting the legislation.

Trump put intense pressure on five Republican senators who joined with Democrats to advance the resolution last week and ultimately prevailed in heading off passage of the legislation. Two of the Republicans — Sens. Josh Hawley of Missouri and Todd Young of Indiana — flipped under the pressure.

Vice President JD Vance had to break the 50-50 deadlock in the Senate on a Republican motion to dismiss the bill.

The outcome of the high-profile vote demonstrated how Trump still has command over much of the Republican conference, yet the razor-thin vote tally also showed the growing concern on Capitol Hill over the president’s aggressive foreign policy ambitions.

Democrats forced the debate after U.S. troops captured Venezuelan leader Nicolás Maduro in a surprise nighttime raid earlier this month.

Trump had hurled insults at several of the Republicans who advanced the legislation, calling Sen. Rand Paul of Kentucky a “stone cold loser” and Sens. Lisa Murkowski of Alaska and Susan Collins of Maine “disasters.” Those three Republicans stuck to their support for the legislation.

Trump’s fury underscored how the war powers vote had taken on new political significance as the president also threatens military action to accomplish his goal of possessing Greenland.

The legislation, even if it had passed the Senate, had virtually no chance of becoming law because it would eventually need to be signed by Trump himself. But it represented both a test of GOP loyalty to the president and a marker for how much leeway the Republican-controlled Senate is willing to give Trump to use the military abroad.

Democratic Sen. Tim Kaine, who has brought a series of war powers resolutions this year, accused Republicans of burying a debate about the merits of an ongoing campaign of attacks and threats against Venezuela.

“If this cause and if this legal basis were so righteous, the administration and its supporters would not be afraid to have this debate,” Kaine said in a floor speech.

Hawley, who helped advance the war powers resolution last week, said that Trump’s message during a phone call was that the legislation “really ties my hands.” The senator said Secretary of State Marco Rubio told him Monday “point blank, we’re not going to do ground troops.”
