California Gov. Gavin Newsom has called President Donald Trump's military intervention in Los Angeles an assault on democracy. Meanwhile in Texas, the GOP governor is putting the National Guard

Amid ongoing tensions over the Los Angeles protests, Trump signed a congressional resolution on Thursday blocking California’s ban on the sale of gas-guzzling cars by 2035, dealing a blow to Newsom’s bid to crack down on pollution.

The governors of Illinois, Minnesota and New York testified Thursday before the House Oversight Committee, which has been investigating sanctuary jurisdictions.

Newsom says Trump’s LA actions marks the onset of a much broader effort to overturn political and cultural norms.

President Donald Trump said on Monday he would support the arrest of California's Gavin Newsom, in a dramatic escalation of a growing conflict with the Democratic governor over immigration protests that roiled Los Angeles over the weekend.

Trump deployed 4,000 National Guardsmen and 700 Marines to LA against the wishes of Newsom and Bass. Newsom sued the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

Lawyers for the Trump administration and Gov. Gavin Newsom will make their case in a Thursday afternoon hearing in San Francisco.

Three Democratic governors are defending their responses to the migrant crisis​ and dispute claims of failing to cooperate with federal authorities, according to remarks prepared for a congressional panel.
