We are seeing this from various stories including this one and stories about Ocasio-Cortez, where the media is framing the situation as an "aggressive" or "fringe" or "insurgent" faction is being pitted against the "moderate" group of congresspeople.

I can even say that I understand that caution about not wanting the investigations to appear overtly political. Well, everything is political because it is politics and government. HOWEVER, there is a legitimate reason to be looking into the situation because Trump's actions indicate that there is wrongdoing. If the investigations and evidence show that nothing is happening, then Democrats, unlike Republicans, will cease and move on to other things because that is how Democrats govern.
