Believe whatever bullshit you want. trump told them to vote against it ( didn't want his ego bruised ) and they followed orders from their king.Again, just. because Republicans supported Ukraine in seperate legislation does not mean they supported a combined Border-Ukraine Funding legislation. Democrats tied the two together to have their cake and eat it too. They wanted to show the American People that they were seemingly trying to solve the border crisis and that it was the Republicans blocking them knowing that Republicans would back Ukraine funding separately.
This is how Washington really works. Unfortunately for the Democrats, the American people saw right through it.
