Jared Kushner, a senior White House adviser and son-in-law of President Trump, said in a closed-door meeting Monday that he did not collude with Russians during Trump's campaign.

Afterward, U.S. Sen Ron Wyden, D-Ore., released a statement calling on Kushner to testify under oath to Congress and provide emails, financial documents and other records supporting his denials.

"He has an obligation to be transparent with all relevant documents to back up his claims," Wyden said of Kushner.

Kushner did tell congressional committees via his 11-page statement that he had several contacts with Russians during the Trump campaign and transition. He said none of the meetings were improper.

"I did not collude, nor know of anyone else in the campaign who colluded, with any foreign government," said Kushner, 36. He added that he has "nothing to hide" and will cooperate with investigators.

Wyden, often an opponent to Trump and his appointees, questioned whether Kushner should be taken at his word. He said Kushner's description of his business relationships with Russians is "incomplete at best" and that the White House aide has "repeatedly concealed information" about his business dealings and foreign ties.

"There should be no presumption that he is telling the whole truth today," Wyden said.

Kushner said administration officials have checked his phone records and they show no evidence corroborating press reports that he had two phone conversations with the Russian ambassador in 2016.

Paul Manafort, former head of the Trump campaign, and Donald Trump Jr., the president's eldest son, avoided subpoenas to testify under oath and at a public hearing this week, instead brokering a deal with Senate Judiciary Committee leaders to provide documents and private testimony ahead of any public hearings.
