ACT for America, a group that the Southern Poverty Law Center says is anti-Muslim, and the Council on American-Islamic Relations, whose mission is to enhance the understanding of Islam, have at least one thing in common: they’re each holding an event at the same Marriott hotel in Arlington, Va., just a few weeks apart.

Marriott International has been under fire over its decision to allow ACT for America to hold its annual conference at the Crystal Gateway Marriott on Oct. 2 and Oct. 3. Arne Sorenson, the president and chief executive officer of Marriott, this week defended the decision to keep that booking, citing the reservation by CAIR as evidence of even-handedness.

“The fact that they’re having a meeting with us, or using our hotel, obviously in no respect means we support their point of view or that we’ve made a judgment about their point of view,” Mr. Sorenson said of ACT for America in an appearance at the Skift Global Forum, a travel industry conference, in New York on Wednesday. “I shudder to think that we really expect that my role, or that Marriott’s role is going to be to say, ‘You know what? Your views are not acceptable in our hotels, and her views are.’ ”

He added that the company had received emails accusing it of harboring terrorists because of the booking by CAIR, held this year on Oct. 28.
