President Trump again took aim at San Juan Mayor Carmen Yulin Cruz on Saturday afternoon after accusing her of being a bad leader.

"Results of recovery efforts will speak much louder than complaints by San Juan Mayor. Doing everything we can to help great people of PR!" Trump tweeted.

The president is spending the weekend at his golf club in Bedminster, N.J., and his latest tweet about Cruz marks his 20th of the day, most of which have been about Puerto Rico.

Cruz criticized the Trump administration for its slow response to the crisis in Puerto Rico, which is reeling from Hurricane Maria.

In response to Cruz's comments, the president unleashed several tweets slamming Cruz earlier Saturday.

"The Mayor of San Juan, who was very complimentary only a few days ago, has now been told by the Democrats that you must be nasty to Trump," Trump tweeted.

"Such poor leadership ability by the Mayor of San Juan, and others in Puerto Rico, who are not able to get their workers to help. They want everything to be done for them when it should be a community effort. 10,000 Federal workers now on Island doing a fantastic job," he said in subsequent tweets.
