The president reportedly made a “profanity-laced” call to the vulnerable Republican senator on Thursday, sources told The Hill. Collins was one of five GOP senators to join Democrats in advancing a resolution on the War Powers Act from committee to the floor, which passed in a 52-47 vote earlier in the day.

The largely symbolic vote follows Collins' opposition in November to a resolution that would have required the president to seek congressional authorization to use military force in Venezuela. The Republican has expressed support for the U.

President Donald Trump blasted Republican senators who voted in favor of a War Powers Resolution on Thursday.

U.S. Sen. Susan Collins said she is supporting a resolution reaffirming the need for congressional approval for any future military action in Venezuela.

The war powers resolution will need another vote in the Senate before it becomes official. Still, the five defectors' rebellion served as a sharp rebuke.

This is a significant switch for Collins; she opposed a similar resolution in November, which failed to pass 51-49.
