Just a token handfull. My guess is maybe 1 or 2 in the senate (empahsis on "maybe," I cannot name one senator that is trustworthy), maybe up to 15 in the house. MTG, Nunes, and Louis Gohmert are solid, to pick a few examples.
There are 2 senators I trust Rand Paul and Kennedy from Louisiana!! Jim Jordan is another house member I trust so we have maybe 5 out of 300 in both houses!,
