Democrats sent a letter, spearheaded by Sen. Richard Blumenthal (D-Conn.), to Grassley requesting the hearings and asking that he issue subpoenas if they won't volunteer to testify publicly and under oath.

“This is an essential step toward getting us the answers that we need to fulfill our important oversight responsibilities," the senators wrote.

Trump Jr. has said the meeting ended up being about Russian adoption policy and was a waste of time.

Democrats said Grassley has already concluded private interviews of individuals in the meeting, bolstering the need to pivot to public hearings.

Trump Jr. previously met with committee staffers.

"Committee members have long been led to believe that they would have the chance to question witnesses directly — to follow up on the many questions raised by the staff interviews and to ensure that witnesses testify publicly and under oath," the senators wrote.

The letter comes as the Judiciary Committee's Russia probe has become increasingly fractured.
