Rep. Greg Walden (OR-2), the top Republican on the powerful House Energy and Commerce Committee, announced that he will retire at the end of this Congress. The Oregon congressman is the 17th House Republican to announce retirement this cycle.

House Democrat Rep. Katie Hill (CA-25) also announced her decision to resign her seat following confirmed reports on her inappropriate relationship with a campaign staffer and a House Ethics investigation into allegations of another inappropriate relationship with a current employee of her congressional office. Hill defeated Republican Steve Knight in the 2018 election, flipping the seat blue for the first time in 26 years.
