Trump expected to sign cyber security executive order Tuesday: source

President Donald Trump is expected to sign an executive order on cyber security on Tuesday, a source familiar with the situation said, marking the first action to address what he has called a top priority of his administration.

The order is expected to commission several different reviews of the government's offensive and defensive cyber capabilities, according to two other sources briefed on a draft of the order that circulated last week.
