President Donald Trump’s son-in-law Jared Kushner will tell a Senate panel later that neither he nor any member of the Trump campaign team colluded with Russian officials over the US election.
He will say he had no improper contacts and had not relied on Russian funds to finance his business activities.
Mr Kushner released his opening statement ahead of the panel meeting.
The Senate, along with the House and a special counsel, are all investigating Russian interference in the election.
Mr Kushner, 36, is a senior adviser to the president and was in charge of the Trump campaign’s digital strategy. He is married to Mr Trump’s daughter, Ivanka.
Mr Kushner, who keeps a very low media profile, will attend a session on Monday before the Senate Intelligence Committee, and then appear before the House version on Tuesday.
