Former FBI Director James Comey’s testimony Thursday to the Senate Intelligence Committee could force Robert Mueller, the special counsel leading an investigation into Russian election meddling, to question President Trump directly about his encounters with Comey.

Mueller’s office, the White House and Trump’s private lawyer all remained silent Thursday evening about the possibility that the special counsel could soon require the president to submit for an interview. But legal experts suggest Comey’s testimony exposed too many inconsistencies with the president’s public statements for Trump to avoid an interview with Mueller in the coming months.
