WASHINGTON — The White House on Tuesday asked Congress for $5 billion to ease a fiscal crisis striking the government of Puerto Rico in the wake of Hurricane Maria.

Puerto Rico’s central government and various municipalities and other local governments are suffering unsustainable cash shortfalls as Maria has choked off revenues and strained resources. The administration’s request, so far delivered informally, would provide $4.9 billion for Puerto Rico and its local jurisdictions.

The White House also requested $150 million to help Puerto Rico with the 10 percent match required for Federal Emergency Management Agency disaster relief.

A senior administration official confirmed the request, requiring anonymity because it is not yet official. The official stressed that jurisdictions other than Puerto Rico are eligible, though draft language sent to Capitol Hill limited the request to U.S. territories.

On Saturday, Puerto Rico Gov. Ricardo Rossello sent a letter to lawmakers asking for $500 million for the community disaster loan program, which is designed to help local governments deal with tax revenue shortfalls caused by disasters. He requested almost $4 billion in other aid.

“In addition to the immediate humanitarian crisis, Puerto Rico is on the brink of a massive liquidity crisis that will intensify in the immediate future,” Rossello wrote.

Puerto Rico was already suffering from a lengthy recession and its government was beset with fiscal struggles to begin with. A financial control board is overseeing its debt problems and austerity plans.
