Four-term congressman Katko has announced that he will not seek re-election in 2022.
The moderate conservative crossed party lines for notable votes including on Biden's Infrastructure Bill.
Of the 10 GOP Reps. who voted to impeach Trump, Katko is the third to announce retirement. Others have been stripped of leadership roles. The GOP has been reduced to a cult, where those insufficiently loyal to Trump are purged.
Katko's highly contested district is likely to be redrawn by the Democratic-controlled NY State Legislature to favor Democratic challengers.
