Twenty Democratic-led states filed a lawsuit Wednesday against the Federal Emergency Management Agency, challenging the elimination of a long-running grant program that helps communities guard against damage from natural disasters.

Pennsylvania is part of a coalition of 20 states that announced Wednesday it was suing the Trump administration for shutting down natural disaster funding through FEMA. Here's what we know.

FEMA announced in April that it was ending the funding to eliminate “waste, fraud and abuse.” The program saved taxpayers more than $150 billion over 20 years, the plaintiffs said.
