(BREITBART) — The Santa Clarita Valley Signal announced Sunday it is endorsing incumbent Republican Steve Knight (R-CA) over Democrat challenger Katie Hill in California’s 25th congressional district because she refused to stop a “Democratic political agitator” from bullying the paper.

In a scathing editorial, “Fed Up with Bullies, We Endorse Steve Knight,” the Signal argues that it has been generous to Hill in its coverage — even spiking negative stories — but that she refused to stop a campaign of harassment and slander:

[A] Democratic political agitator associated with the Hill campaign, masquerading as a concerned citizen, has done everything he could to try to unfairly discredit The Signal. He has lied, misrepresented and conflated facts in order to relentlessly attack this paper, the publisher, his family and the editor. This is such a hotly contested race that Hill’s advocates ed left-leaning publications to attack us with unfounded accusations and material intentionally taken out of context.
