Should I withdraw/stop putting into my 401k?

I keep up with most of the dumpster fire that is current US news but I'm sorta lost on this one. I contribute to my 401k every week and have a few thousand saved up, as well as stock in the company I work for. Is all of the bad news referring to the stock market crashing? Is this general across the board or more company-specific? I consider myself decently politically educated but not so much economically.
