U.S. President Donald Trump commented Thursday on the Washington Post report stating that he is being investigated for possibly obstructing justice in the probe into Russia's alleged involvement in the U.S. election race and the possible ties between members of his election campaign and Moscow.
According to the paper, Daniel Coats, the current director of national intelligence, Mike Rogers, head of the National Security Agency, and Rogers's recently departed deputy, Richard Ledgett, agreed to be interviewed by Mueller's investigators as early as this week.
A spokesman for President Donald Trump's lawyer says a Washington Post report that the president is under investigation for possible obstruction of justice came from an "inexcusable and illegal" FBI leak.
Former FBI Director James Comey confirmed during testimony that the president was not personally under investigation in the Russian Federation probe, but according to sources for the Washington Post, that changed after he was sacked.
The White House noted in a statement last month that FBI Acting Director Andrew McCabe testified that "there has been no effort to impede our investigation to date". House Speaker Paul Ryan and other Republican leaders publicly said they thought the investigation should be allowed to run its course, and that firing the special counsel would be a mistake.
Mueller's office has taken up that work, and the preliminary interviews scheduled with intelligence officials indicate that his team is actively pursuing potential witnesses inside and outside the government.
Sessions' testimony came in the wake of fired FBI Director Comey's assertion that he believed he was sacked by Trump as part of an effort to influence the agencies' investigation into Russia's meddling in the presidential polls.
According to the Post's sources, the Justice Department began an investigation into Trump's actions shortly after he dismissed Comey, which the president himself admitted was because of the Russian Federation investigation. Both men refused to do so.
Asked about the Comey memo, Burr said the committee got "clarity" on whether it can obtain the document, but he would not say whether that means the committee will receive it.
Rosenstein told the Senate Appropriations Committee Tuesday that Mueller would have "the full degree of independence that he needs to conduct that investigation appropriately" and that he would not follow an order to fire the special counsel "unless I believe those are lawful and appropriate orders".
Mr Grassley's office said the letter was in response to a recent letter from Ms Feinstein requesting that the committee seeks details from senior Federal Bureau of Investigation leadership about Mr Comey's interactions with Mr Trump before he was sacked.
While a sitting president is unlikely to face criminal prosecution, obstruction of justice could form the basis for his impeachment in Congress.
Mr Trump fired Mr Comey last month, citing the intelligence chief's decision to announce previous year that Hillary Clinton was no longer under investigation.
