Former New York City Mayor Rudolph Giuliani is joining President Donald Trump’s legal team, providing advice on how to deal with the special counsel’s investigation into Russian interference into the 2016 election, attorney Jay Sekulow confirmed to NBC News on Thursday. "Rudy is great," Trump said, according to a statement provided by Sekulow. "He has been my friend for a long time and wants to get this matter quickly resolved for the good of the country." “I’m doing it because I hope we can negotiate an end to this for the good of the country and because I have high regard for the president and for Bob Mueller,” Giuliani said in an interview with the Washington Post.
