Donald Trump Jr., former President Donald Trump's eldest son, appeared before the Jan. 6 select committee on Tuesday for a voluntary interview, multiple sources familiar with his appearance confirmed to ABC News.

       ABC News first reported last month that Trump Jr. was expected to appear before the committee, as it wraps up its investigatory phase and prepares for at least eight public hearings next month.

       The committee declined to comment.

       The president's son was the latest member of the Trump family to meet with the committee after Ivanka Trump and Jared Kushner, both of whom served as senior White House advisers to former President Donald Trump, were also interviewed in recent weeks.

       Donald Trump Jr. speaks during the first day of the Republican convention in Washington, Aug. 24, 2020.

       Kimberly Guilfoyle, Trump Jr.'s fiance, has also met with the committee twice. Sources said the second interview was at times contentions and focused in part on the fundraising efforts around Trump's "Save America" rally on Jan. 6, 2021.

       Trump Jr.'s text messages are among those that former Trump chief of staff Mark Meadows turned over to the committee, sources have said.

       "He's got to condemn [the riot] ASAP," Trump Jr. told Meadows in a text message, according to Rep. Liz Cheney, R-Wyo., the vice chair of the panel who quoted extensively from text messages sent to Meadows, among others.

       "I'm pushing it hard," Meadows replied. "I agree."

       "We need an Oval Office address," Trump Jr. said in a follow-up message. "He has to lead now. It has gone too far and gotten out of hand."
