Republican Sen. Lindsey Graham told House Minority Leader Nancy Pelosi and her Democratic caucus on Friday that there would not be a deal on a funding bill unless it included appropriations to construct a wall on the U.S.-Mexico border.

“To Nancy Pelosi and the House Democrats,” Graham tweeted. “No Wall Money, No Deal.”

To Nancy Pelosi and the House Democrats:

No Wall Money, No Deal.

The House passed a stopgap funding bill on Dec. 20 that included $5.7 billion for a border wall, however, with a 51-seat majority in the Senate, Republicans fell short of the necessary 60 votes needed to send it to President Donald Trump’s desk for signature.

Senate Minority Leader Chuck Schumer vowed to kill the legislation on arrival in the Senate, and consequently, a government shutdown has been in effect since funding expired Dec. 21.
