Major U.S. labor unions are organizing truck drivers to help with relief efforts in Puerto Rico as the island continues to grapple with the devastation wrought by Hurricane Maria last week.
The Teamsters union and the AFL-CIO, a federation of more than 50 unions, are working together to recruit truckers to travelto Puerto Rico and help distribute a stockpile of relief supplies
Thousands of shipping containers full of food, water, and medicines were sitting unused at Puerto Rico's Port of San Juan.
Relief workers haven't been able to distribute the goods, in part because only about 20% of Puerto Rico's truck drivers have reported back to work since Hurricane Maria swept through, according to a representative for Puerto Rican Gov. Ricardo Rosselló.
On top of that, Puerto Rico has a shortage of diesel fuel, which is needed to power the semi-trucks. Downed power lines and debris still litter roadways, blocking routes. Even contacting local drivers is an issue because cell service blackouts still cover the majority of the island.
Teamsters spokesman Galen Munro told CNN that the union hopes to get more drivers on the ground next week.
Yulín Cruz pushed back against Trump's assertion this week that relief work in Puerto Rico was a "good news story."
"This is, damn it, this is not a good news story," Yulín Cruz told CNN. "This is a 'people are dying' story. This is a 'life-or-death' story. This is, 'there's a truckload of stuff that cannot be taken to people' story."
On Saturday, Trump used Twitter to criticize her "leadership ability" and claimed Puerto Ricans "want everything to be done for them when it should be a community effort."
Yulín Cruz responded to the tweets in an interview with MSNBC on Saturday: "I was asking for help," she said. "I wasn't saying anything nasty about the President."
