Donald Trump has issued a series of attack tweets aimed directly at his own Attorney General, Jeff Sessions.

When Trump first nominated Sessions to be the next US attorney general (AG), he described the then senator from Alabama as a "world-class legal mind" saying that "Jeff is greatly admired by legal scholars and virtually everyone who knows him."

Fast-forward to July 2017, and now a day seldom passes without the president attacking the man he nominated.

It comes amid growing speculation that Trump may fire Sessions following his decision to recuse himself from the Russian investigation currently taking place in the Justice Department.

After lavishing praise on Sessions, Trump has issued regular tweets condemning the actions taken by the Attorney General.

In a tweet issued on Tuesday morning (25 July), Trump said: "Attorney General Jeff Sessions has taken a VERY weak position on Hillary Clinton crimes (where are E-mails & DNC server) & Intel leakers!"

And in another tweet, he quoted the Fox TV host Sean Hannity who had said that Ukraine was working on efforts to "sabotage the Trump campaign" to which the president followed up with "where is the investigation AG?"

It comes after Trump revealed in an interview that he was "disappointed" with the decision for Sessions to recuse himself.

The digs at Sessions have come at the same time as a new wave of attacks on Hillary Clinton.

Also on Tuesday morning, Trump suggested that the Clinton campaign had given money for the emails investigation to be eased, he said: "Problem is that the acting head of the FBI & the person in charge of the Hillary investigation, Andrew McCabe, got $700,000 from H for wife!!

It comes on a stressful day for politicians on the Capitol with a crunch vote on the future of Obamacare to take place today.
