President Donald Trump is moving swiftly to act on his immigration promises with little internal restraint, determined to test the bounds of his executive authority in order to fulfill the promises of his reelection campaign.

Tensions flared in Los Angeles late Monday after Trump escalated military presence in the region against the wishes of California Gov. Gavin Newsom.
