President Donald Trump went off on fellow Republicans in two tweets Sunday afternoon, accusing his party members of doing "very little to protect their President."

"As the phony Russian Witch Hunt continues, two groups are laughing at this excuse for a lost election taking hold, Democrats and Russians!" Trump wrote shortly after 4 p.m. ET.

"It's very sad that Republicans, even some that were carried over the line on my back, do very little to protect their President," he said in a second tweet shortly after.

Trump was at the Trump National Golf Club in Potomac Falls, Virginia, on Sunday but had returned to the White House about an hour before firing off the tweets.

Trump piled on criticism for Republicans over healthcare later Sunday night.

"If Republicans don't Repeal and Replace the disastrous ObamaCare, the repercussions will be far greater than any of them understand!" Trump tweeted.

The tweets came one day after Trump pointed out on Twitter his "complete power to pardon" people convicted of wrongdoing in his capacity as president.

"While all agree the U. S. President has the complete power to pardon, why think of that when only crime so far is LEAKS against us.FAKE NEWS," Trump tweeted on Saturday.

Saturday's tweet came on the heels of an explosive Washington Post report saying that the president and his legal team were looking into the limits of his pardoning power and that Trump had raised the question of whether he could pardon himself as investigations by Congress and special counsel Robert Mueller into the Trump campaign's ties to Russia widened in scope.
