President Donald Trump said on Friday the White House would soon release a letter regarding a classified document crafted by Democrats to refute a Republican memo that alleged FBI bias against Trump in its Russia probe.

Trump, speaking to reporters after an event in the Oval Office, did not provide any details on what the letter would say.

It was not immediately clear whether he was referring to a letter to Congress detailing a decision to declassify and release all or parts of the Democrat memo, a letter of denial, or something else.
