Democratic Sen. Dick Durbin has accused President Donald Trump of discrediting the Office of the President.
Durbin's comments came after Trump alleged that former President Barack Obama had wiretapped his phones at Trump Tower during the 2016 presidential election campaign, CNN reported.
"Donald Trump is destroying the credibility of the Office of President 140 characters at a time," Durbin told CNN.
In his tweets, Trump wrote that he "just found out" that Obama had "my 'wires tapped' in Trump Tower."
"Is it legal for a sitting President to be ‘wire tapping’ a race for president prior to an election?" another tweet from Trump read, according to the Washington Post. "Turned down by court earlier. A NEW LOW!"
He also tweeted, "This is Nixon/Watergate."
No evidence for the allegations has yet been provided. White House press secretary Sean Spicer referred March 5 to "reports" that mentioned "potentially politically motivated investigations" during the 2016 campaign. But none of the media reports the White House cited contained information about politically motivated surveillance.
FBI director James Comey asked the Justice Department to issue a statement denying Trump's allegations, but the department did not do so.
The White House called March 5 for an investigation by Congress into Trump's allegations.
But Durbin dismissed any suggestion of wrongdoing.
"This charge that he has made about some wiretapping before the election without a scintilla of evidence has been refuted not only by the former president but the national head of intelligence and the head of the Federal Bureau of Investigations," Durbin added to CNN.
A spokesman for Obama stated March 4 that the former president never authorized a wiretap of Trump or any other American citizen. "Any suggestion otherwise is simply false," he added, according to the Post.
Durbin suggested other motives were involved in the call for a congressional inquiry.
"The Republicans in Congress still want to take this seriously. Why? So they can avoid a serious investigation, an independent, transparent investigation, of the Russian involvement in the last election," said Durbin.
Trump has consistently rejected calls to stop using Twitter. He said Feb. 28 that Twitter "does allow me to go around dishonest media," according to Fortune.
"Most of the people that want me to stop it are the enemies, I'll be honest with you," Trump said in the interview with Fox. "If I felt the media were honest, all of it, or most of it, I wouldn't do it. But it is a modern day form of communication."
