The National Border Patrol Council (NBPC) mocked Vice President Kamala Harris on Friday, calling her a "clown" as Title 42's expiration date looms.

"In 6 days the massive crush of illegal aliens coming through our border will make the last 2 years look like amateur hour," the Border Patrol Union wrote in a Twitter post.

Title 42, a Trump-era policy that allows the swift expulsion of illegal immigrants from the U.S., will expire on May 11 and tens of thousands of migrants are expected to seek entrance into America after it is lifted. 

"Biden doesn't have one clue about how to contain what he's unleashed. He has a clown running DHS and a worse clown as VP. Watch what happens," NBPC said in an effort to draw attention to the ongoing crisis at the southern border.
