The American Civil Liberties Union says it has raised more than $10 million since Saturday after it filed challenges to President Donald Trump’s ban on immigrants from some countries.

Anthony Romero, the group’s executive director, said the influx of donations was an “unprecedented” response to Trump’s executive order restricting entry into the United States from seven Muslim-majority countries, Yahoo News reported.

“With Republicans controlling both houses of Congress and the Democrats in disarray and lacking any spine, the two pincers (opposing Trump) have to be litigation and citizen action,” Romero said.

Federal Judge Ann Donnelly on Saturday night granted a request by the ACLU that blocked deportations that Trump had ordered on Friday.

Romero said he thought many people in the Justice Department, including holdovers from the Obama administration, would have difficulty defending the order.
