Flake joked on Twitter he would sit with Baldwin even though “it might end up a whereas clause in a AZ GOP censure resolution.”

A number of Republicans have defended McCain after the censure from the state Republican Party at a weekend meeting, including Sarah Palin earlier in the day.

Flake will watch the speech Tuesday night alongside Baldwin as part of a tradition started four years ago that urged lawmakers to sit next to a member of the opposite party. Sens. Lisa Murkowski (R-Alaska) and Mark Udall (D-Colo.), who spearheaded the move in 2011, have said they did so to remind lawmakers they are not serving individual states or parties.
