President Donald Trump pressed senior aides last June to devise and carry out a campaign to discredit senior FBI officials after learning that those specific employees were likely to be witnesses against him as part of special counsel Robert Mueller’s investigation, according to two people directly familiar with the matter.

In testimony to the Senate Intelligence Committee on June 8, recently fired FBI Director James Comey disclosed that he spoke contemporaneously with other senior bureau officials about potentially improper efforts by the president to curtail the FBI’s investigation of alleged collusion between the Trump campaign and Russia to interfere in the 2016 U.S. presidential election.

Mueller is investigating whether Trump’s efforts constituted obstruction of justice.
