Donald Trump Jr. slated to speak to Senate Intelligence Committee

This will be the third time the president's eldest son is questioned.

The president’s eldest son told investigators that he spoke to his father shortly after reports revealed the 2016 Trump Tower meeting last summer. He infuriated Democrats by declining to detail those conversations with then-candidate Trump, saying the conversation was protected by attorney-client privilege because lawyers for both were present at the time.

"Counsel made a claim of attorney-client privilege,” California Rep. Adam Schiff, the top Democrat on the House Committee, told ABC News after the interview. “This is a central communication about a very pivotal meeting and a conversation between father and son is not subject to the attorney-client privilege. So, uh, we intend to persist and make sure we get answers to that question."

The sources said he also told lawmakers that he did not engage in any follow-up communications with WikiLeaks beyond the direct message exchanges on Twitter he recently revealed after the correspondence was first reported by The Atlantic.

Wednesday might not be Trump Jr’s final appearance at the Capitol, as some senators have pushed for him to testify publicly about his Trump Tower meeting and activities during the presidential campaign.
