Trump's 'Praise be to Allah' post

The President's unusual choice of language has drawn criticism from both political allies and religious leaders.

While the post was intended as a fierce warning to Tehran, the inclusion of an Islamic phrase on a Christian holiday has baffled observers.

Some suggest the rhetoric is an attempt to mock the Iranian regime, while others see it as a sign of an increasingly erratic leadership style.

The post has further fueled calls for the invocation of the 25th Amendment by some of the President's most vocal critics.
