"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?" Trump asked, apparently rhetorically, on Twitter.
"Despite that, we play the game because I, unlike the Democrats, have done nothing wrong!" he added in a second tweet.
Trump's claim that he has the power to pardon himself follows arguments made by Rudy Giuliani, one of Trump's lawyers, who said Sunday that should Trump choose to issue a self-pardon, it "would just be unthinkable and it would lead to, probably, an immediate impeachment."
"President Trump has no need to do it. He didn't do anything wrong," Giuliani told NBC's Meet the Press Sunday morning television program.
Trump and his administration have been focused on discrediting a special counsel probe into Russia and the Trump campaign that is being led by Special Counsel Robert Mueller.
The American president claimed last week, without evidence, that the special counsel investigation would seek to interfere in this year's midterm elections.
It remains unclear what, if any, information Trump based his claim on, but it fits into his and his administration's efforts to discredit Mueller's probe, which the president has consistently derided as a "witch hunt".
