President Trump's demand for investigation may lead to 'constitutional crisis'

"If anyone did infiltrate or surveil participants in a presidential campaign for inappropriate purposes, we need to know about it and take appropriate action", Mr Rosenstein said in a statement.

As Nunes has persisted, anonymous authorities resisting his demand commenced a leak campaign with stories planted in the New York Times and the Washington Post (story linked here) this past Friday evening, both full of information all but identifying Stefan Halper as an informant working with the Federal Bureau of Investigation to probe the Trump campaign.

But when asked whether there was an informant on the campaign, Giuliani told CNN, "I don't know for sure, nor does the president, if there really was one", though he said they have always been told there was "some kind of infiltration". "They said September, which is good for everyone, because no one wants this to drag into the midterms".

As a pair of Post articles, dated May 8 and 9, explained, the DOJ has refused to provide the documents, concerned that the safety of the US citizen source could be endangered, and that ongoing intelligence investigations could be compromised.

"This would be the culmination of the investigation into the president", Giuliani said.

White House spokeswoman Sarah Sanders said Sunday she had nothing to add to the President's tweets.

It is not certain that Trump will sit for an interview with Mueller, though the president has publicly said he would.

It said Mr Mueller's investigators had questioned witnesses in Washington, New York, Atlanta, Tel Aviv and elsewhere regarding possible foreign help to the campaign.

Meanwhile, House Democrats stood by the Justice Department following the President's demand for an inquiry into the department's actions regarding the Trump campaign.

Trump made the order amid days of public venting about the special counsel investigation, which he has deemed a "witch hunt" that he says has yielded no evidence of collusion between his campaign and Russian Federation.

Attorney General Jeff Sessions, along with congressional Republicans, had already requested an investigation to review whether FBI and Justice Department officials had abused their surveillance powers.

"The IG shouldn't be pursuing political charges made by the president based on zero evidence", argued MSNBC legal analyst Matthew Miller in response to Rosenstein's statement.

The request came after Trump tweeted on Sunday that he planned to order an investigation into whether the FBI or DOJ "infiltrated or surveilled" his campaign "for political purposes".

Hours later, Deputy Attorney General Rod Rosenstein asked the Justice Department to step in, according to reports.

"This claim by the president and the suggestion by Giuliani that there is a political spy embedded in the Trump campaign is nonsense and you hear it in the same terms that Trump often speaks which is "people are saying, ' or" I'm hearing, ' or 'we're being told, ' he said". Trump tweeted yesterday afternoon. The panel didn't publicize the subpoena, but the Justice Department released a letter it sent to Nunes rejecting the request for information "regarding a specific individual".

Mr Trump, who has long complained the Russian Federation probe overstepped its bounds, referred to reports his eldest son, Donald Trump Jr, met in August 2016 with an envoy representing the crown princes of United Arab Emirates and Saudi Arabia.
