“Republican Senate must get rid of 60 vote NOW!,” Trump said in one of his five tweets Saturday morning on the issue. “It is killing the R Party, allows 8 Dems to control country. 200 Bills sit in Senate. A JOKE!”

The Senate has 52 Republican senators and 48 Democrats and independents who vote, or caucus, together.

Several of the measures this week — including the one Tuesday to begin debate on bills and amendments — required just 51 votes. However, others, including an amendment from Texas GOP Sen. Ted Cruz that would have garnered support from the Senate Republican conference’s conservative wing needed 60 votes and failed.
