The Republican chairman of a US congressional committee on intelligence said on Sunday that he has seen "no evidence" that President Donald Trump's campaign colluded with Russia during the run up to the 2016 elections.
Based on "everything I have up to this morning -- no evidence of collusion," said US Representative Devin Nunes, head of the House Intelligence Committee, speaking to Fox News on a television program on Sunday.
Nunes also said the panel would investigate the intelligence leak of the probe on former national security adviser Michael Flynn's ties to Russia.
Nunes, however, said the leak involving Michael Flynn was a crime and that the panel was probing whether other names were leaked.
"The one crime we know that's been committed is that one: the leaking of someone's name ...," Representative Devin Nunes, chairman of the House of Representatives Permanent Select Committee on Intelligence, told Fox News Sunday.
Trump fired Flynn from the post of his former national security adviser last month after he failed to disclose that he met Russia's ambassador before Trump took charge on January 20.
The Congressional panel chief's remarks come a day before FBI director James Comey is due to appear before the panel, facing lawmakers seeking answers about Trump's potential Russia ties and the president's accusation of wiretapping by his predecessor Barack Obama.
Nunes, House of Representatives Speaker Paul Ryan and other leading Republicans have said no such wiretap took place.
Nunes repeated on Fox News that he did not believe any such wiretapping took place.
The Russian government has rejected an accusation by US intelligence agencies that it worked to influence the election in Trump's favor.
