Trump often talks about making staff changes without following through, so those who have spoken with the president cautioned that a change may not be imminent or happen at all. What is clear is that Trump remains furious that the attorney general recused himself from the investigations.

"So why aren't the Committees and investigators, and of course our beleaguered A.G., looking into Crooked Hillarys crimes & Russia relations?" Trump tweeted Monday. His tweet came just hours before his son-in-law, White House senior adviser Jared Kushner, travelled to Capitol Hill to be interviewed about his meetings with Russians.

Trump's intensifying criticism has fueled speculation that Sessions may resign even if Trump opts not to fire him. During an event at the White House, Trump ignored a shouted question about whether Sessions should step down. The attorney general said last week he intended to stay in his post.
