The U.S. Department of Justice has confirmed there's no evidence that former President Obama wiretapped Trump Tower.

President Trump in widely publicized tweets in March accused former President Obama of wiretapping him.
According to a Newsweek report on Saturday, the U.S. Department of Justice recently contradicted Trump's assertion.
The publication notes, "In a stunning filing last night, the Department of Justice stated in a court case that neither the FBI nor its National Security Division ever wiretapped Trump Tower, contradicting a bombshell claim" made by Trump on Twitter.
Newsweek goes on to say that while former FBI director James Comey has stated in the past that the FBI did not wiretap Trump, this is the "first time the Department of Justice has officially denied the substance" of the allegation.
The tweets in question were posted by Trump on March 4.
"Terrible! Just found out that Obama had my 'wires tapped' in Trump Tower just before the victory," Trump said. "Nothing found. This is McCarthyism!"
The president continued, "How low has President Obama gone to tapp my phones during the very sacred election process. This is Nixon/Watergate. Bad (or sick) guy!"
Obama has denied any such activity.
“Neither President Obama nor any White House official ever ordered surveillance on any U.S. citizen," Obama's spokesman Kevin Lewis said in a March statement. "Any suggestion otherwise is simply false.”
