President Trump could see the next year of his life made extraordinarily difficult by Republican lawmakers who have chosen to retire rather than seek re-election in the frenzied political environment his presidency has helped create.

One such lawmaker, Sen. Bob Corker, R-Tenn., has already spent weeks chiding Trump for requiring the supervision levels of an “adult day care.” And another, Sen. Jeff Flake, R-Ariz., announced his early retirement on Oct. 24 with a speech that called on fellow Republicans to reject the president’s behavior and fight an erosion of GOP values.
