Trump says lawmakers are 'wasting their time' if border security talks don't include a wall or barrier

President Donald Trump said Wednesday that any congressional negotiations on border security were a waste of time if they didn't include a "wall or physical barrier." Lawmakers are trying to hash out a deal that would avert another partial government shutdown when the government again runs out of funding Feb. 15.

What are the details?

In a tweet, Trump wrote, "If the committee of Republicans and Democrats now meeting on Border Security is not discussing or contemplating a Wall of Physical Barrer, they are Wasting their time!"

On Dec. 22, the U.S. federal government ran out of funding and went into a partial shutdown that lasted for 35 days. Roughly 800,000 federal workers went without pay during that time.

Trump has repeatedly said he will not sign any bill to fund the federal government that does not include $5.7 billion in funding for a wall on the border between the U.S and Mexico. Democrats in Congress have so far been unwilling to agree to any bill that contains funding for a border wall.

On Monday, 2020 presidential hopeful Sen. Kamala Harris (D-Calif.) said she would not vote in favor of any bill that included funding for a border wall "under any circumstances."

On Jan. 25, Trump announced a bill that reopened the government for three weeks. If Congress does not come to an agreement by then, the government will go back into a partial shutdown. As part of these negotiations to come up with a new bill to fund the government, 17 Democrats and Republicans from both the House of Representatives and the Senate have met to try to come up with some sort of border security deal that could pass Congress and still be acceptable to Trump.
