President Trump on Tuesday fired off a series of tweets about border security, vowing to circumvent Congress and order the US military to build his long-promised border wall “if Democrats do not give us the votes to secure our Country.”

Hours before meeting Democratic leaders to discuss funding for the wall, the president touted his efforts to shore up security along the US-Mexico border.

“Despite the large Caravans that WERE forming and heading to our Country, people have not been able to get through our newly built Walls, makeshift Walls & Fences, or Border Patrol Officers & Military,” he said in one of five tweets about the subject.

“They are now staying in Mexico or going back to their original countries,” he continued. “Ice, Border Patrol and our Military have done a FANTASTIC job of securing our Southern Border.

“A Great Wall would be, however, a far easier & less expensive solution. We have already built large new sections & fully renovated others, making them like new,” he added.

“The Democrats, however, for strictly political reasons and because they have been pulled so far left, do NOT want Border Security. They want Open Borders for anyone to come in. This brings large scale crime and disease.

“Our Southern Border is now Secure and will remain that way,” he said, adding that he looked forward to his meeting at the White House with House Democratic leader Nancy Pelosi of California and Senate Democratic leader Chuck Schumer of New York ahead of a Dec. 21 deadline to shut down some government agencies.

“In 2006, Democrats voted for a Wall, and they were right to do so. Today, they no longer want Border Security. They will fight it at all cost, and Nancy must get votes for Speaker. But the Wall will get built,” he said.

“People do not yet realize how much of the Wall, including really effective renovation, has already been built,” he added.

“If the Democrats do not give us the votes to secure our Country, the Military will build the remaining sections of the Wall. They know how important it is!”

Trump wants the next funding package to include at least $5 billion for it — an idea Democrats have flatly rejected.

Pelosi and Schumer have urged the president to support a bill that includes a half-dozen government funding bills largely agreed upon by lawmakers, along with a separate measure that funds the Department of Homeland Security at current levels through Sept. 30.

The homeland bill includes about $1.3 billion for fencing and other security measures at the border.
