US President Donald Trump Twitter

US President Donald Trump on Monday branded the probe of the Special Counsel Robert Mueller’s investigation as “unconstitutional” and declared that he has an “absolute right” to pardon himself of any crime.

While both claims lack strong legal foundation, according to most experts, they signalled that the president is doubling down against Mueller’s probe into campaign collusion with Russia and whether Trump sought to obstruct justice.

“As has been stated by numerous legal scholars, I have the absolute right to PARDON myself, but why would I do that when I have done nothing wrong?” he said on Twitter.

“The appointment of the Special Counsel is totally UNCONSTITUTIONAL! Despite that, we play the game because I, unlike the Democrats, have done nothing wrong!” he added in a second tweet.
