Trump: No politician has ever been treated worse than me
President Donald Trump has said no politician in history has been treated worse or more unfairly than he has.
He lashed out at his "critics and naysayers" in his first comments after former FBI Director James Comey reportedly released a memo revealing Trump had asked him to drop the investigation into former National Security Adviser Michael Flynn.
President Trump fired Mr Flynn earlier this year for misleading top White House officials about his contacts with Russian officials.
The House of Representatives oversight committee has set a hearing for May 24 to investigate whether US President Donald Trump interfered in an FBI probe, and has asked James Comey to testify.

In an address to the newest group of US Coast Guard officers, President Trump urged the 195 graduates in the Class of 2017 to "put your head down and fight, fight, fight" when life presents them with challenges and adversity.
He said: "Look at the way I've been treated lately, especially by the media.
"No politician in history, and I say this with great surety, has been treated worse or more unfairly.
"You can't let them get you down. You can't let the critics and the naysayers get in the way of your dreams."
"I guess that's why we won," he said, before continuing to offer the graduates his advice.
There were calls today for Mr Trump's impeachment.
Congressman Al Green took to the house today to call for President Trump's impeachment.
Senator John McCain also waded into the row, saying: "I think we've seen this movie before.
"I think it's reaching the point of Watergate size and scale."
The White House has denied the latest report on Comey's memo, which landed amid a furore over the president's recent Oval Office meeting with Russian diplomats in which Mr Trump is said to have disclosed classified information.
The White House has said it was "wholly appropriate" for President Trump to share the information.
White House spokesman Sean Spicer said that Trump was "very clear" that the account of his discussion with Comey was not accurate.
He said Trump is meeting with four candidates for the role of FBI chief on Wednesday.
