Duke also spoke alongside Puerto Rico's governor, Ricardo Rossello, and Rep. Jennifer Gonzalez, the delegate from the territory, during a press conference Friday.

"Sometimes the gov might be giving the appearance of not moving fast enough", Bossert said.
"Well, maybe from where she is standing it's a good news story".
She upbraided acting Homeland Security Secretary Elaine Duke, who described the federal response as "a good news story". "When you're drinking from a creek, it's not a good news story".

About a week after closing in advance of Hurricane Maria, Ardent Mills community mill in San Juan, Puerto Rico, is back in partial operation. Local officials say it could take anywhere from four to six months until power is fully restored across the island of almost 3.5 million people. "Big decisions will have to be made as to the cost of its rebuilding", Trump tweeted Friday morning.
The department announced the trip Thursday evening after Duke's "good news" comments at the White House earlier that day.
The Federal Emergency Management Agency, the lead agency responding to the storm's aftermath, is a part of DHS.

Not exactly the sensitive thing to say to people still fighting for their very survival. "People come to get water for their families". She worked as an adviser to the San Juan mayor and the president of Puerto Rico's House of representatives, according to her biography.
FEMA, which is leading the relief effort, has sent 150 containers filled with relief supplies to the port of San Juan since the hurricane struck on September 20, said Omar Negron, director of Puerto Rico's Ports Authority.
She asked US President Donald Trump to act quickly on hurricane relief and urged him to deal with the island's debt crisis.
