Newsom has been drawing attention to and challenging Trump's initiatives with social media posts that directly mock his style

Gavin Newsom formally kicked off his push Thursday to redraw California’s congressional maps in response to a Republican-led effort in Texas, setting up the next stage of his fight against both the Trump administration and a coalition of gerrymandering opponents within the state.

"If you've got issues with what I'm putting out, you sure as hell should have concerns about what he's putting out as president," said Newsom.

Democrats in California’s Legislature presented a united front in support of Gov. Gavin Newsom’s retaliatory redistricting effort on Monday.

Santa Rosa really is the key for Northern California, because it's such a big population base,’ Assemblymember Chris Rogers said.

Republicans can move ahead with redrawing Texas’ congressional districts now that Democratic lawmakers have returned to the state.

As Texas hurtles toward a flashpoint on a GOP effort to redraw congressional districts, California Democrats are answering with a plan of their own.

Gov. Newsom is working to determine the true motives behind Trump's decision to deploy federal agents outside the governor's news conference in Little Tokyo this past week.
