In a Christian Broadcasting Network interview released Saturday, the 2008 vice presidential candidate says the administration is withholding information on Egyptian President Hosni Mubarak's likely successor.
The 82-year-old leader wants to rule until September elections.
Palin said in the Friday interview the U.S. must find out who is "behind all the turmoil" and that "we should not stand" for a government led by the Muslim Brotherhood.
Referencing a 2008 campaign ad, Palin said Egypt was the White House's "3 a.m. phone call" but it "went right to the answering machine."
She says the U.S. must say whom it stands with, "and we do not have all that information yet."
