Former FBI Director James Comey will be pressed on whether President Trump sought to obstruct his probe on Russia. Comey, who led the investigation into Russia's alleged meddling in the presidential eleciton, will appear before the Senate Intelligence Committee on Thursday. Trump fired Comey last month only four years into his 10-year-long term. "I want to know what kind of pressure - appropriate, inappropriate - how many conversations he had with the president about this topic?" Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, told CBS's "Face the Nation" program on Sunday.
