"In 2014 he ran as a Democratic candidate for Congress, hoping to represent the 42nd Congressional District of California." (from the end of the article)Which means that he has bought into the Democrat politics and policies that has empowered the criminal thugs and disarmed their victims. And he was in Washington to further a career promoting those politics and policies.
It's embarrassing, but I've had democrats in my family. Some are parasitic socialists, and I despise them, but some see the party label as the best path to office and use that to promote responsible and limited government once in office. Not all democrats are evil thugs, like Obama, who use power to bully Christians and patriots, while rewarding their big donors with our tax dollars.
