In a 20-page letter to Special Counsel Robert Mueller obtained by The New York Times and published Saturday, President Trump's lawyers argue the president can not obstruct justice because he has constitutional authority over all federal investigations, including the Russian Federation probe.
Like almost every Republican or former Trump staffer who appeared on TV Sunday morning, advisor and former Campaign Manager Corey Lewandowski addressed the document sent to investigators by the Trump administration regarding the President's powers and authority with regard to legal matters.
Over on CNN, Preet Bharara, the former U.S. Attorney in Manhattan, who Trump fired less than two months into his administration, agreed with Giuliani that it would be politically perilous for the president to self-pardon.
"That's another really interesting constitutional question: Can the president pardon himself?" he added. "It would be an open question, but gosh, I think it would probably get answered by, 'Gosh, that's what the Constitution says, and if you want to change it, change it'". The New York Times published the January 29 letter this weekend. "Pardoning other people is one thing, pardoning yourself is another".More news: Bryson DeChambeau one ahead at Memorial, with Justin Rose four back

Former New Jersey Gov. Chris Christie agreed on Sunday, telling "This Week" that there is "no way" Trump will pardon himself. "Having him testify demeans the office of the president before the world".
Part of Mr Mueller's investigation is looking at whether Mr Trump sought to criminally obstruct it, in particular with the sacking of ex-National Security Adviser Michael Flynn and former FBI director James Comey, and with his reaction to Attorney General Jeff Sessions' recusal from the investigation.
Rudy Giuliani also spoke at length explaining the amount of authority the justice department holds over President Trump as compared to Congress. "If the president were to pardon himself, he'll get impeached".
Mr Trump also said he was considering pardoning lifestyle maven Martha Stewart and commuting the prison sentence of former IL governor Rod Blagojevich, convicted of corruption charges.
