Rep Jose Serrano, D-NY, no seeking re-election in 2020

As chairman of a House Appropriations subcommittee with jurisdiction over the departments of Justice and Commerce, Serrano said in a statement that until his term ends he would work on advancing climate change research, making the justice system more fair and assuring an accurate 2020 Census count.

That's the second one today. Other one was D-NM Tom Udall.
