- Ambassador Sergei Kislyak (above). Brief meeting of "pleasantries" in April 2016 in Washington. Meeting at Trump Tower on 1 December. Discussed Syria and trying to improve relations. Mr Kushner insists he did not suggest a "secret back channel" for communication or discuss sanctions. Mr Kislyak's term ended on Saturday
- Sergei Gorkov. Mr Kushner says he met the banker on 12 December at the request of Mr Kislyak, who presented him as a man with direct links to President Vladimir Putin. Mr Kushner insists he did not discuss sanctions, business interests or specific policy issues and has had no contacts with him since
- Guccifer400. Mr Kushner says he received a "random email" trying to extort 52 bitcoins in exchange for not publishing Mr Trump's tax details. Mr Kushner says he ignored the email
- Natalia Veselnitskaya. Mr Kushner said he had not spoken to the lawyer before or since the June 2016 meeting and had forgotten about it until an email exchange involving President Trump's son, Donald Jr, came to light last month. He says: "No part of the meeting I attended included anything about the campaign, there was no follow up to the meeting that I am aware of, I do not recall how many people were there (or their names), and I have no knowledge of any documents being offered or accepted."
Mr Kushner was not expected to invoke his Fifth Amendment right against self-incrimination at the Congress meetings.
In his statement, he says: "I am happy to share information with the investigating bodies. I have shown today that I am willing to do so and will continue to co-operate as I have nothing to hide."
His statement concludes: "Hopefully, this puts these matters to rest."
Mr Kushner was also not expected to be under oath on Monday. However, what he says could be used against him at a later date and may well be passed to the special counsel, Robert Mueller, to help his investigation.
Adam Schiff, the top Democrat on the House intelligence panel, said: "There's a lot we want to know. We have a lot of ground to cover."
Mr Trump Jr and Mr Manafort had been scheduled to appear before Congress on Wednesday to testify but that has been delayed indefinitely as lawyers negotiate on the documentation and information to be discussed.
President Trump has repeatedly denied any collusion with Russia.
He continued his tirade against the investigation process on Sunday, tweeting: "As the phony Russian Witch Hunt continues, two groups are laughing at this excuse for a lost election taking hold, Democrats and Russians!"
Russia has also denied any involvement.
