President Trump confirms he is under investigation

The Washington Post this week reported, not only that the president is under investigation for possible obstruction of justice, but also that the FBI inquiry is examining the business and financial dealings of the president's son-in-law Jared Kushner.

If Mueller's investigation were to find evidence that Trump committed a criminal offense, the Department of Justice (DOJ) would not indict the president as a matter of precedent and instead present the evidence to members of Congress, who would then determine whether the crime warranted articles of impeachment.

On Wednesday, the Washington Post reported Mueller is investigating Trump directly, over alleged obstruction of justice.

The President than went on to renew his attack on his presidential election opponent Hillary Clinton and her husband, former USA president Bill Clinton.

The Post, citing unnamed sources, said the investigation into the president's own conduct began shortly after Trump fired Comey on May 9.

The special counsel appointed to probe alleged Russian meddling in the 2016 United States presidential polls is now also investigating President Donald Trump for possible obstruction of justice, according to a media report.

Rosenstein can fire Mueller, but that doesn't make him the one investigating Trump.

Mr Trump previously claimed he was the victim of a "witch hunt" in May after Mr Mueller, a former FBI director, was appointed to lead an investigation into his campaign's alleged ties to Russian Federation.

Several congressional panels are also investigating the Russian Federation issue, which has cast a shadow over the early months of Trump's presidency.

Trump slammed the development as political witch hunt.

Mr Comey, who was sacked on May 9, told the Senate Intelligence Committee last week he believed President Trump dismissed him to undermine the FBI's Russian Federation probe.

That tweet from this morning seemed to be a swipe at Deputy Attorney General Rod Rosenstein, who chose former FBI Director Robert Mueller to lead the Special Counsel probe of Russian election interference. "Nice", Mr Trump wrote on Twitter earlier, later repeating his accusation the probe was a "witch hunt".

"With this in mind please immediately suspend any deletion, modification, overwriting, or other possible destruction of the information described above, including electronic information, and take all reasonable measures to preserve this information", the memo said, according to the Times.
