Washington (CNN) President Donald Trump said Saturday that the Senate should approve a government spending package that includes funding for border security and a wall before the August break or not go on recess.

"The Senate should get funding done before the August break, or NOT GO HOME. Wall and Border Security should be included. Also waiting for approval of almost 300 nominations, worst in history. Democrats are doing everything possible to obstruct, all they know how to do. STAY!," the President tweeted.

Congress passed a $1.3 trillion spending bill in March that will fund the government through the end of September. That legislation included $1.6 billion in border security funding.

But Trump has made clear he wants more money allocated, and he even floated the possibility at a rally last month that he might support a government shutdown in the fall if Congress does not provide what he believes to be adequate funding for border security.

It is unclear why the President did not mention the House of Representatives in his tweet on Saturday, but the margin of Republican control of the Senate is narrower than in the House, making it potentially more challenging for Trump's priorities to win passage in the upper chamber.
