California, a coalition of other states and the city of San Francisco have sued the Trump administration over President Trump’s executive order aimed at ending birthright citizenship, calling it unconstitutional. The swap that freed two Americans was brokered before President Biden left office Monday, according to a Trump administration official.

Those policy changes were expected to start rolling in fast in the first hours and days of his second term after a campaign in which Trump vowed to launch the largest deportation operation in the country’s history.
