I was in the left hand lane doing the speed limit.

You were impeding traffic. It is the law here that you have to move out of the left lane if you are not passing. Doesn’t matter if you are doing the speed limit. —

Not in a two-lane construction zone.

Oh most definitely. You are not the arbiter of the law or speed limit. If you are not actively passing, get out of the left lane.
