Donald Trump has threatened to investigate Barack Obama “the way they’ve looked into me”.

In statements given in the Oval Office, the president said the Democrats “want to investigate, they want to go fishing”, and suggested the attention given to his ties to Russia and possible obstruction of justice, could apply to other presidents.

“We want to find out what happened with the last democrat president. Let’s look into Obama the way they’ve looked at me from day one,” Mr Trump told reporters.

“They’ve looked into everything we’ve done. They could look into the book deal that president Obama made. Let’s subpoena all of his records.”

The president went to return to one of his common themes, Hillary Clinton.

“Let’s subpoena all of the records having to do with Hillary Clinton, and all of the nonsense that went on with Clinton and with her foundation and everything else,” he said. “We could do that all day long.”

While the Clinton Foundation has been the subject of much discussion on both sides of the political spectrum, it isunclear what Mr Trump is talking about with regards to Mr Obama’s book deal.

The former president did break records with a highly lucrative book deal in 2017, but a deal itself is not uncommon. In fact, nearly every president in the modern era has released a memoir leaving office, for which they have been paid.

Mr Trump also continued to repeat the lie that Robert Mueller’s report cleared him of all wrongdoing, saying “the document says ‘no collusion’,” which it does not.

In the wake of Mr Mueller’s congressional hearings on Wednesday, the Trump administration and its supporters have latched onto the public opinion, largely curated by specific voices in both traditional and social media, that nothing new or explosive came out of the hearings. In fact, Mr Mueller stated that his report did not absolve the president, and outrightly warned of Russian interference in upcoming elections.

Mr Mueller has a pristine reputation in Washington, where he was previously in charge of the FBI. Throughout his investigation, he and his team have been notoriously tight lipped about what they know and where their investigation has led.

Mr Comey was fired by the president after Mr Trump reportedly asked him to drop his own Russia investigation. Mr Trump has long maintained that the investigation is a "witch hunt".

Mr Rosenstein found himself with that responsibility after then-attorney general Jeff Sessions recused himself from that oversight. AP Mueller investigation: The key figures Attorney general Jeff Sessions's decision to recuse himself from oversight of the special counsel investigation may have cost him his job in the end. Mr Sessions resigned last year, after weathering a contentious relationship with Donald Trump who vocally criticised his attorney general for taking a step back. Mr Sessions recused himself from the oversight citing longstanding Justice Department rules to not be involved in investigations overseeing campaigns that officials were apart of.

Mr Barr's office will be the first to receive the Mueller report when it is finished. His office will then determine what portion or version of that report should be delivered to Congress, and also made public.

Among those crimes, Cohen admitted to facilitating $130,000 in hush money payments to adult film actress Stormy Daniels during the 2016 campaign. Cohen has said he did so at the direction of Mr Trump. Cohen has also admitted that he maintained contacts with Russian officials about a potential Trump real estate project in Moscow for months longer than Mr Trump and others admitted. The talks continued well into 2016 during the campaign, he has said. AP Mueller investigation: The key figures Stormy Daniels has alleged that she had an affair with Donald Trump in 2006, soon after Melania Trump gave birth to Baron Trump. The accusation is of particular importance as a result of the $130,000 hush money payment she received to keep quiet about the affair during the 2016 campaign.

But the president, who Russia was found explicitly to favour in the report, is still mostly maintaining that investigating him at all is an inexcusable affront.

“Frankly, the Republicans were gentlemen. And women,” he told reporters. “When we had the majority in the house, they didn’t do subpoenas all day long, what these people have done. What they’re doing is a disgrace.”
