Half a day after he arrived in Puerto Rico alongside Sen. Chris Murphy to survey the island’s recovery from Hurricane Maria, Sen. Richard Blumenthal said it was clear a lot of work remains to be done.

“The simple blunt fact is that there is a continuing humanitarian and economic crisis here,” Blumenthal said by phone from Puerto Rico Tuesday afternoon, the first day of a two-day trip. “The island is still in triage … in terms of electricity and transportation, triage is the operative word here.”

The senators visited the University of Puerto Rico Hospital in San Juan earlier Tuesday where they learned that many doctors and medical professionals are leaving Puerto Rico for positions elsewhere. Blumenthal said without robust funding to rebuild and repair infrastructure on the island, more professionals will leave, further devastating Puerto Rico’s economy.

“The business community has been sapped of customers, resources and investment,” he said. “It is in danger of becoming an economic wasteland.”

Blumenthal and Murphy have both been critical of the Trump administration’s response in Puerto Rico. More than 100 days after the storm, half the island remains without electricity.

“This state of affairs would be unacceptable if it existed on the mainland United States,” said Murphy, who joined Blumenthal on a conference call with reporters. “We would not accept this ongoing disaster if it occurred on the mainland United States and we shouldn’t accept it here.”

Lawmakers in October approved a $36.5 billion disaster relief package that included aid for Puerto Rico bundled with help for Texas, Florida and other southern states battered by hurricanes, as well as money for wildfire recovery efforts in California.

But Murphy said after meeting Tuesday with representatives from FEMA and the Army Corps of Engineers he found out that none of that money has made it to Puerto Rico yet.

“The people of Puerto Rico are rightly furious at the very slow pace of recovery,” Murphy said. “The Trump administration needs to do better. … Resources are still a major issue.”

Blumenthal joined Sen. Bernie Sanders last month to announce legislation that would send $146 billion in federal funds to Puerto Rico to rebuild the island in a manner similar to the way the Marshall Plan helped Western Europe recover after World War II.

“What the federal government has done here has been sadly and shamefully inadequate,” he said. “The rebuilding of this island will simply not happen in the way it should without adequate resources.”

The House approved an additional $81 billion in disaster relief funds earlier this month, but it has been held up in the Senate amid Democratic objections.

After speaking with reporters, the senators planned to visit a neighborhood in San Juan that remains without electricity before having dinner with Puerto Rico’s governor and other officials.

The pair will have more meetings on Wednesday before returning to Washington.
