The top two lawmakers on the Senate Intelligence Committee joined their House counterparts on Thursday to confirm that there is no evidence to back President Donald Trump’s claim that he was under surveillance by the prior administration.

Chairman Richard M. Burr, a North Carolina Republican, and Vice Chairman Mark Warner, a Virginia Democrat, said in a joint statement there were “no indications” to back up Trump’s assertion.

“Based on the information available to us, we see no indications that Trump Tower was the subject of surveillance by any element to the United States government either before or after Election Day,” the senators wrote.

The statement came the day after the leading Republican and Democratic lawmakers on the House Intelligence Committee said they believed there was no proof Trump was wiretapped during former President Barack Obama’s administration.

Vice President Mike Pence and new Director of National Intelligence Dan Coats declined to answer the Senate Intelligence finding after Coats’ swearing-in ceremony on Capitol Hill Thursday.

“I”m not going to answer any questions today,” Coats said. “It’s a special day for us.

Earlier this month, Trump alleged on Twitter that Obama had wiretapped phones in Trump Tower just before the November election.

Since the tweet, the White House has attempted to backtrack on the claims, even though the president asked the House and Senate Intelligence committees to determine if Obama ordered the bugging.

That investigation is part of an ongoing inquiry into alleged Russian meddling in last year’s election, any ties Trump and his associates had with Russia during the campaign, as well as intelligence leaks.

The House Intelligence Committee will hold its first public hearing to discuss the investigation on Monday.
