"We need to pass a disaster relief package," Rubio told "CBS This Morning" co-host John Dickerson on Wednesday. "What the House passed was not enough. We have to do more; we're working on doing more."

"My biggest concern is that we didn't do enough early in the process at the federal level, because we tried to treat it like a conventional storm and it was not," he added. 

Rubio said he also disagreed with the decision by the Federal Emergency Management Agency to end its free supplies of food and water for Puerto Rico this week.

The Trump administration drew criticism for its response to the massive hurricane last fall. Some said the administration was too slow to provide federal assistance.

The president also publicly feuded with the mayor of San Juan, Puerto Rico, when she criticized his response.

The House passed $15.3 billion in short-term relief in September, followed by a $36.5 billion aid package for both hurricane and wildfire relief in October.
