"You have one Republican who's too weak to stand up to the Democrats," Trump Jr. said of Burr in May.

Sen. Lindsay Graham (R-S.C.), one of the president’s most vocal supporters in the Senate, first publicly advised Trump’s eldest son to ignore the subpoena, then told him to plead the Fifth.

However, after Burr stood his ground on the subpoena, Trump Jr. and the committee reached an agreement for him to testify before the panel Wednesday for two to four hours about six topics, including a June 2016 meeting at Trump Tower and a proposed Trump Tower project in Moscow.

The panel is reportedly interested in questioning Trump Jr. about contradictions between his own 2017 testimony and other witnesses’ statements to the committee and Mueller.

For example, he told the committee that he was “peripherally aware” of the Trump Tower Moscow project, but his father’s former personal attorney Michael Cohen Michael Dean CohenJudge orders Eric Trump to comply with New York AG's subpoena before Election Day A huge deal for campaign disclosure: Trump's tax records for Biden's medical records Our Constitution is under attack by Attorney General William Barr MORE told Mueller that he discussed it with him on several occasions.

The committee has been in contact with Trump Jr. to return for follow-up questions since December but issued the subpoena in April after he twice agreed to voluntarily testify before postponing.

A representative for Trump Jr. did not immediately respond to a request for comment from The Hill. A spokesperson for Burr's office said the office did not discuss witness engagements.
