Trump spokesman Corey Lewandowski confirmed to the AP the proposal would apply to Muslims who are tourists as well as those seeking immigration visas. Another campaign spokeswoman told The Hill the ban would also apply to Muslim-Americans traveling abroad.

The White House, through spokesman Josh Earnest, quickly condemned the comment. Earnest told MSNBC Monday afternoon that the proposal is “entirely inconsistent with the kinds of values that were central to the founding of this country.”

“Not only is it contrary to our values, but if we actually want to have a comprehensive strategy for combatting extremist elements in the Muslim community, then we actually need to work with the Muslim community, work with Muslim leaders to root out those voices and to root out that messaging,” Earnest said.

In the full statement (below), Trump quoted polling by the Center for Security Policy, an anti-Muslim think tank whose founder, Frank Gaffney is known for raising alarms about “creeping Sharia law” and for accusing U.S. officials of having ties to the Muslim Brotherhood. The poll itself was widely discredited.

Trump’s statement comes as recent attacks in Paris and in San Bernardino, California, have inflamed anti-Muslim rhetoric and prompted fears about immigrants, particularly concerning the U.S.’s Syrian refugee program. Trump’s statement to end all Muslim immigration goes further than previous GOP proposals, including Sen. Rand Paul’s (R-KY) call that immigration from the Middle East should be halted.
