Here is the list of senators who are retiring this cycle (sorted alphabetically by state):

Senator Party State Reason for retirement
Richard Shelby Republican Alabama He will be 88 on Election Day 2022
Roy Blunt Republican Missouri He is a old-style dealmaker and there are no deals to be made any more
Richard Burr Republican North Carolina He is compromised by an inside-trading scandal
Rob Portman Republican Ohio He is a moderate who can't stand the dysfunctional Senate
Pat Toomey Republican Pennsylvania He would probably lose if he ran

Here are the announced House retirements, sorted on PVI (Cook Partisan Voting Index) based on the 2020 districts.
In other words, it is based on the old districts, before reapportionment. The PVIs will change once new districts are drawn,
but all we have now are the old ones. Any seat between R+5 and D+5 is a swing district that has to be fought over,
even more so if occupied by the "wrong" party.

Representative Party District PVI Reason for retirement
Kevin Brady Republican TX-08 R+28 He hit the term limit for chairing the Ways and Means Committee
Tom Reed Republican NY-23 R+6 Got enmeshed in a #MeToo-type scandal
Ann Kirkpatrick Democratic AZ-02 R+1 Her seat could be vulnerable after redistricting
Tim Ryan Democratic OH-13 D+1 Running for the seat that Sen. Rob Portman (R-OH) is vacating
Charlie Christ Democratic FL-13 D+2 He is running for governor
Cheri Bustos Democratic IL-17 D+3 She badly botched her job as chair of the DCCC
Filemón Vela Democratic TX-34 D+10 His seat will definitely be vulnerable after GOP-led redistricting
