The Senate Judiciary Committee has listed Donald Trump Jr. and Paul Manafort as witnesses at a hearing set for next Wednesday.

President Donald Trump‘s eldest son and his former campaign manager have not personally confirmed that they will attend the hearing.

Should they testify, the younger Trump and Manafort will likely face a grilling about a meeting they both sat in on last year at Trump Tower. Trump Jr. took the meeting after getting offered comprising information on then-candidate Hillary Clinton as part of Russia and it’s government’s support for his father’s campaign, according to emails he released.

The Senate Intelligence Committee will also interview Jared Kushner, Trump’s son-in-law and White House advisor, in a closed session on Monday, according to NBC News. He also attended the meeting at Trump Tower.

A spokesman for Judiciary Committee Chairman Sen. Chuck Grassley, R-Iowa, confirmed that the hearing to which Trump Jr. and Manafort were invited will be public.
