President Trump on Tuesday defended U.S. Immigration and Customs Enforcement from Democratic attacks, and said ICE is needed to wipe out the “infestation” of MS-13 gang members who have entered the country.

“When we have an ‘infestation’ of MS-13 GANGS in certain parts of our country, who do we send to get them out? ICE!” Trump tweeted Tuesday morning. “They are tougher and smarter than these rough criminal elelments that bad immigration laws allow into our country. Dems do not appreciate the great job they do! Nov.”
