A federal judge's ruling blocking President Trump’s executive order restricting birthright citizenship is just the beginning of a blitz of litigation set to play out in the coming weeks.

Six lawsuits have been filed claiming Trump’s order, issued as part of a flurry of immigration actions during his first day in office, violates the 14th Amendment and federal citizenship laws.

“There’s been a lot of litigation,” Justice Department attorney Brad Rosenberg joked as he attempted to recall all the cases at a Thursday teleconference in a Maryland suit, “so my apologies, Your Honor.”

Later in the day, U.S. District Judge John Coughenour became the first to block Trump’s restrictions, at the conclusion of a brief hearing in Seattle on four states’ challenge. Coughenour, an appointee of former President Reagan, agreed Trump’s order is likely unconstitutional.

"The harms are immediate, ongoing, and significant, and cannot be remediated in the ordinary course of litigation,” reads Coughenour’s ruling, which remains in effect until for 14 days.

When asked about the ruling in the Oval Office, Trump said the government "obviously" will appeal.

“They put it before a certain judge in Seattle, I guess, right? And there’s no surprises with that judge," Trump said.

Democratic state attorneys general, pregnant mothers and immigration rights groups have now filed a total of six lawsuits against Trump’s order. They are set to crescendo in courtrooms across the country in a series of written briefings and hearings........
