What exactly is Rudy Giuliani's role?

Despite a disastrous debut last week in his new role as a member of President Trump’s legal team—including making contradictory statements, revealing White House untruths, and being publicly upbraided by his client—Rudy Giuliani was back at it over the weekend.

It’s unclear what Giuliani’s aim was. If he was hoping to clean up his mess and make the president look good, he didn’t have a great morning. If he was hoping to make news, he succeeded. Among other statements, Giuliani said that Trump would not have to comply if Special Counsel Robert Mueller subpoenaed him (this is debatable, but most lawyers agree it would not hold up); admitted he was shaky on matters of both fact and statue—“I am focused on the law more than the facts right now,” he said in an interview with CNN Sunday; and seemed to call the president a fool.

“I’m facing a situation with the president and all the other lawyers are, in which every lawyer in America thinks he would be a fool to testify, I’ve got a client who wants to testify,” Giuliani said on ABC’s This Week.
