"Everybody is arguing whether or not it is a BAN. Call it what you want, it is about keeping bad people (with bad intentions) out of country," he tweeted.
Trump signed an executive order Friday to block refugees from entering the U.S. for 120 days and immigrants from seven predominantly Muslim nations away for three months. Iran, Iraq, Syria, Sudan, Libya, Yemen and Somalia are the countries impacted.
White House press secretary Sean Spicer dismissed the idea that Trump imposed a ban.

But both Spicer and Trump have recently referred to the executive order as a ban. Trump tweeted earlier this week in defense of his order, "If the ban were announced with a one week notice, the 'bad' would rush into our country during that week. A lot of bad 'dudes' out there!"
Spicer used the term ban to describe the order when describing it Monday while speaking at an event at George Washington University recorded on C-SPAN.
"One, the ban deals with seven countries that the Obama administration had previously identified as needing further travel restrictions," Spicer told School of Media & Public Affairs Director Frank Sesno

The administration has been criticized for suggesting that the ban will guarantee safety that statistics do not support.
