I'd rather worry about the head guy, President of the United States of America, as he holds all the power, unlike congress members that have to rely on voting process to introduce laws/policies.
Is this the latest talking point by conservative mainstream media (Fox News) and conservative youtube shills? Downplay no kings protest (and the message being sent by it) against Trump by pointing out that there are politicians who have been in politics for longer than Trump has been? Weak sauce.
Trump is actively shaping and changing the country - congress members you speak of, are merely following his lead.
