President Trump's attorney Rudy Giuliani said on Tuesday that he wants the parameters of an interview between the president and special counsel Robert Mueller to be set by May 17, which is the one-year mark for when Mueller was appointed to probe possible ties between the Trump campaign and Russia's efforts to influence in the presidential election. 

"You need a sort of action-forcing event. I think that's a good one for us, is the special counsel," Giuliani told NBC's Kristen Welker.
