WASHINGTON (Reuters) - The U.S. Justice Department on Friday said it delivered documents to congressional committees responding to their request for information that could shed light on President Donald Trump’s claims that former President Barack Obama ordered U.S. agencies to spy on him.

The information was sent to the House and Senate intelligence and judiciary committees, said Sarah Isgur Flores, a Justice Department spokeswoman.

The chairman of the House Intelligence Committee, Republican Devin Nunes, said in a statement late on Friday that the Justice Department had “fully complied” with the panel’s request.

A government source, who requested anonymity when discussing sensitive information, said an initial examination of the material turned over by the Justice Department indicates that it contains no evidence to confirm Trump’s claims that the Obama administration had wiretapped him or the Trump Tower in New York.

The House Intelligence Committee will hold a hearing on Monday on allegations of Russian meddling in the U.S. election. Federal Bureau of Investigation Director James Comey and National Security Agency Director Mike Rogers will testify and are expected to field questions on Trump’s wiretap claim.

Leaders of both the House and Senate intelligence committees, including from Trump’s Republican Party, have said they have found no evidence to substantiate Trump’s claims that Obama ordered U.S. agencies to spy on Trump or his entourage. The White House has publicly offered no proof of the allegation.

On Monday, the House panel sent the Justice Department a letter asking for copies of any court orders related to Trump or his associates which might have been issued last year under an electronic surveillance law or a wide-ranging anti-crime statute.
