"Because this is our lives now, some portion of our politics are devoted to questions like, can a sitting president be indicted, and can the president be subpoenaed? This is obviously a major issue for President Trump's new lead lawyer in the Russia probe, Rudy Giuliani, formerly known as America's Mayor and now known as someone who will "get his facts straight" at some point. Yes, Giuliani has had a torrid time of it on the cable news circuit: He admitted Trump knew about the Stormy Daniels payment, exposing the president's continual lies, and he echoed Trump's own admission that James Comey's firing had to do with The Russia Thing. The latter has the pungent aroma of obstruction of justice, which is guaranteed to be part of the line of questioning Trump will see if he sits down with Special Counsel Robert Mueller. The question is whether Trump will agree to the interview, whether he can be compelled to sit for it through a subpoena, or whether he can avoid it entirely. Giuliani joined CNN's Chris Cuomo Friday morning to suggest there was no way a sitting president could be compelled to testify. He then promptly melted down when Cuomo played back a clip of Giuliani saying the opposite when the president in question was Bill Clinton"
