President Trump said Wednesday that lawmakers are “wasting their time” if the border security talks that begin today don't include funding for a physical barrier at the southern border.

“If the committee of Republicans and Democrats now meeting on Border Security is not discussing or contemplating a Wall or Physical Barrier, they are Wasting their time!” Trump tweeted Wednesday morning.

Trump agreed last week to reopen the federal government if lawmakers use the next three weeks to negotiate an agreement on border security. Trump has pushed for a border wall, but there's no guarantee he'll get one — every Democrat opposes funding for the wall, and many Republicans are lukewarm on the idea.

Trump has threatened that if an agreement is not reached to allocate the $5.7 billion for border wall construction, he will declare a national emergency in order to spend emergency funds on the wall, without asking Congress.

Trump on Wednesday also boasted about his foreign policy improvements, including an upcoming meeting with North Korean leader Kim Jong Un , set for the end of February.

“North Korea relationship is best it has ever been with U.S. No testing, getting remains, hostages returned. Decent chance of Denuclearization,” Trump tweeted in reference to the recent strides made with the authoritarian nation.

“Time will tell what will happen with North Korea, but at the end of the previous administration, relationship was horrendous and very bad things were about to happen. Now a whole different story. I look forward to seeing Kim Jong Un shortly. Progress being made-big difference!”

The president also said that since taking office he has made “tremendous progress” in the Middle East, and last month deemed victory over ISIS as he ordered troop withdrawal from Syria.

“When I became President, ISIS was out of control in Syria & running rampant," Trump continued in a string of tweets Wednesday morning. “Since then tremendous progress made, especially over last 5 weeks. Caliphate will soon be destroyed, unthinkable two years ago.”
