America First Legal, a conservative legal group, filed a brief Tuesday backing the Department of Justice‘s decision to cut nearly $1 billion in grants to left-wing groups as it faces a lawsuit over the cancellations.

In May, a coalition of left-leaning groups filed a lawsuit against the Justice Department, which had canceled $820 million in grants in April. Judge Amit Mehta of the United States District Court for the District of Columbia granted the DOJ’s motion to dismiss the lawsuit last week despite the coalition of groups having asked for an injunction pending appeal to the U.S. Court of Appeals.
