Special counsel Robert Mueller on Wednesday will make a statement about his investigation into Russian interference in the 2016 presidential election, the Justice Department announced.

The on-camera appearance will be the first time Mueller has spoken publicly about the probe since he was named special counsel two years ago. The Justice Department did not elaborate on what he plans to say but said he will not take questions.

House Democrats are seeking to have Mueller testify before the Judiciary Committee, but lawmakers have thus far not reached an agreement with the special counsel regarding possible testimony.

The White House was alerted on Tuesday night that Mueller may make a statement on Wednesday, according to a senior White House official. It’s not clear if the Judiciary panel was alerted about Mueller’s appearance ahead of time.

President Trump has wavered on whether Mueller should testify before Congress, but Attorney General William Barr has said he has no objections to such a hearing.
