Incoming White House Chief of Staff Reince Priebus said some aspects of the Islamic faith are "problematic" while defending former Lt. Gen. Michael Flynn's controversial comments about Muslims.

Asked on ABC whether future National Security Adviser Flynn's view that Islam is a political ideology that hides behind being a religion is in line with President-elect Trump's view of Islam, Priebus answered "I think so."

"Clearly there are some aspects of that faith that are problematic and we know them; we've seen it," Priebus said. "It certainly isn't a blanket for all people of that faith, but Mike Flynn is one of the most highly respected intelligence officers in America. Certainly no one can deny that."

The future White House chief of staff did not explicitly define the aspects of Islam he thought "problematic" and what, if anything, the president-elect would do about it as president.
