Presumptive Republican presidential nominee Donald Trump is giving consideration to retired Lt. Gen. Michael Flynn as a potential vice-presidential running mate, a Republican source familiar with the process told Reuters on Saturday.

For weeks Trump has conducted a high-profile canvassing of Republican political stalwarts as part of his running-mate search, but he has also made clear he is looking at what a military leader would bring to the ticket.

The source, speaking on condition of anonymity, said Flynn has emerged as a possibility, confirming reports in the New York Post and The Washington Post. The Trump campaign had no comment.

Flynn, though a fierce critic of Barack Obama, is a registered Democrat, according to The Washington Post.

The thinking is that Flynn, who has been a foreign-policy adviser to Trump, would be able to help Trump in the area of national security at a time of challenges abroad like the threat from Islamic State militants.
