As usual, if Crenshaw is opening his mouth he's telling half-truths to his audience for his own benefit.
Adam Kinzinger doesn't have a record of voting with Trump moreso than most members of the Freedom Caucus and it's not close to 99% of the time. I'm guessing Dan Crenshaw considers himself a legislator yet he's not sponsored a single bill that has been passed into law. He is, however, a performance artist and quite proud of it when not in bipolar mode.
Agreed; as you pointed out a few weeks ago there isn't much reason to trust Crenshaw--he's playing the straight-shooter type in this interview, but is just as likely to don another persona for a different audience.
