Senate Republicans moved to block a bipartisan effort aimed at curbing the Trump administration’s military action in Venezuela, handing President Trump a key foreign policy victory.

Senators Josh Hawley and Todd Young reversed their earlier support following intense pressure from the White House, including direct outreach from Trump and Secretary of State Marco Rubio. The last-minute flips highlight Trump’s grip on the GOP and his readiness to publicly attack party members who challenge his agenda.
