Members of the House Intelligence committee want to review the Twitter exchanges between Donald Trump Junior and Wikileaks. To see a full picture of those discussions - Twitter may get a subpoena.

Earlier this week, Don Junior released screenshots of those exchanges which date back to September 2016.

In October, the president's eldest son wrote WikiLeaks:

"What's behind this Wednesday leak I keep reading about?"

WikiLeaks responded, "Hey Donald, great to see you and your dad talking about publications."

Don Jr.'s lawyer has downplayed the significance of those messages.

While the House pursues its investigation, the Senate is also probing Russia's involvement, in addition to the inquiry special counsel Robert Mueller is leading.

The Senate Judiciary committee notified the lawyer for the President's son-in-law and White House advisor, Jared Kushner, that he withheld information about his contacts with WikiLeaks.

They are now seeking documents about a Russian backdoor overture and dinner invite.

Ike Kaveladze, a Soviet-born businessman, spent several hours in special counsel Mueller's office Thursday.

Kaveladze attended a 2016 meeting with Kushner and Trump Jr. where they expected to discuss dirt on Hillary Clinton.
