Senior US lawmakers said Wednesday they had seen no evidence to support President Donald Trump's claim that his predecessor Barack Obama wiretapped his New York home and office building.
"We don't have any evidence that that took place," said Devin Nunes, Republican chairman of the congressional committee conducting a probe into the allegation, at a press conference.

he heads, "I don't think there was an actual tap of Trump Tower," said Nunes, whose committee is also conducting an investigation into suspected Russian interference in last year's US election.
Nunes' conclusion was echoed by the panel's top Democrat, Adam Schiff.
"To date I've seen no evidence that supports the claim that President Trump made that his predecessor had wiretapped he and his associates at Trump Tower," Schiff told reporters at the press conference.
"Thus far, we have seen no basis for that whatsoever."
On March 4, Trump sparked a furor when wrote on his @realDonaldTrump Twitter account that Obama had tapped into communications at Trump Tower, New York home to the president and first family, before the November 8 election.

"Terrible! Just found out that Obama had my 'wires tapped' in Trump Tower just before the victory. Nothing found. This is McCarthyism!"
"Is it legal for a sitting President to be 'wire-tapping' a race for president prior to an election? Turned down by court earlier. A NEW LOW!" he added in a second tweet.
The tweets sparked enormous controversy, in part because it is unprecedented for any US president to accuse a predecessor of a felony crime.
The US president made his allegations claims came just after reports in conservative media made the same claim, leading to suspicions they were his source, which the White House has not denied.
"It deeply concerns me that the president would make such an accusation without basis," said Schiff.
Nunes and Schiff said they do not expect to hear evidence backing up the claim when Federal Bureau of Investigation Director James Comey testifies to the House Intelligence Committee on Monday.
