Aah, my browser addons blocked the lower list, so I only saw the 2 Executive Branch and the 4 Congressional Leadership.
Off the two democrats congressional Leaderships, Nancy Pelosi has 14% and Charles Schumer has 11% in the True category. This in contrast with the republicans that has 12%, 0%, 10% and 5% (trump).
My very first check of that assertion has a fully "True" rating of 20%[1]. And if you count the entire true spectrum it's 73%. And there is not a small sample size. I assume your statement is only regarding the current executive branch?
I also tried a spot check of the Congress, but my very first check also failed to meet your criteria[2]. The problem with this is that it undermines your entire point. The executive branch has the most strained relationship with objective reality, and that stems from the demands of the current president. They're basically forced to lie for political reasons because the truth is too damaging.
