"By the way, there are no problems in America. Everybody is doing well. Things are fair and decent, and no one died in Puerto Rico," Biden quipped at the beginning of remarks at an economic summit in Washington, D.C.

Biden, who did not name Trump during his remarks calling for higher wages, also blasted "all of this foolishness that’s going on with this phony populism and this naked nationalism that’s being promulgated right now."

"The lack of a value set, lack of treating people with dignity is because when things are tough for people economically who work hard, there are sometimes charlatans who come along who try to find a reason for those people to blame whatever’s happening to them on the other," he said.

Biden's latest barbs followed a pair of Thursday morning tweets in which Trump cast doubt on a study that found nearly 3,000 people died as a result of Hurricane Maria, which devastated Puerto Rico last year.

"3000 people did not die in the two hurricanes that hit Puerto Rico. When I left the Island, AFTER the storm had hit, they had anywhere from 6 to 18 deaths," Trump tweeted. "As time went by it did not go up by much. Then, a long time later, they started to report really large numbers, like 3000."

Trump went on to claim without evidence that Democrats were responsible for the increased death toll, speculating that it was part of a plot to make him look "as bad as possible."

.....This was done by the Democrats in order to make me look as bad as possible when I was successfully raising Billions of Dollars to help rebuild Puerto Rico. If a person died for any reason, like old age, just add them onto the list. Bad politics. I love Puerto Rico! — Donald J. Trump (@realDonaldTrump) September 13, 2018

The president's tweets drew swift backlash from members of both parties, with Democrats, Puerto Rican officials and a handful of Republicans denouncing the comments.

Biden is considered a potential candidate for the 2020 presidential nomination, though he has not yet definitively said whether or not he will run.

Trump has welcomed a potential challenge from the former vice president, as the two have traded verbal jabs regularly.
