Excerpt:
Speaker Paul Ryan (R-Wis.) is indicating a willingness to sue Donald Trump if he tries to ban Muslims from entering the United States as president.
In an interview with The Huffington Post published Friday, Ryan didn't rule out suing a Republican president over executive overreach.
"I would sue any president that exceeds his or her powers," he said.
Still, Ryan didn't say directly whether he thought Trump enacting a ban on Muslims entering the U.S. would exceed the limits of presidential authority.
