WASHINGTON – President Donald Trump and San Juan Mayor Carmen Yulin Cruz are trading more insults over the pace of hurricane recovery in Puerto Rico, calling each other "crazed" and "unhinged."

"The crazed and incompetent Mayor of San Juan have done such a poor job of bringing the Island back to health," Trump said during a series of tweets late Monday night about the fate of a disaster relief bill in the Senate.

Cruz quickly fired back, saying the Trump administration continued to provide an inadequate response to the damage wrought by Hurricane Maria in 2017.

"Pres Trump continues to embarrass himself & the Office he holds," she tweeted. "He is unhinged & thus lies about the $ received by PR."

Resuming the argument Tuesday morning, Trump again claimed that "Puerto Rico got 91 Billion Dollars for the hurricane," but it is not clear where he got that figure, and actual spending is not close to that. A FEMA report said it passed the $3 billion mark in public assistance to Puerto Rico in August.

Ricardo Rossello, the governor of Puerto Rico, admonished Trump over his false claim of $91 billion.

"Mr. President: STOP spreading misinformation!" he tweeted. "#PuertoRico has not received $91b (only 300M in permanent work). It's not 'us' vs 'them'. It's about Americans in need."

Trump invoked Cruz in a series of tweets complaining that Democrats blocked a disaster relief package because it did not contain enough assistance for Puerto Rico.

Senate Minority Leader Chuck Schumer, D-N.Y., criticized Trump for urging senators not to provide any more aid to Puerto Rico. The president reportedly told colleagues that "they don't know how to spend the money and they're not spending it wisely."

"They said that Emperor Nero fiddled while Rome burned," Schumer said. "President Trump tweets while Puerto Rico suffers."

The impasse has stalled passage of a $13.5 billion bill that includes assistance to states hit by historic floods, including farm country in Nebraska, Missouri, Kansas and Iowa.

In one of his tweets, Trump said Puerto Rico is receiving assistance, "and now the Dems want to give them more, taking dollars away from our Farmers and so many others. Disgraceful!"

Trump on Tuesday claimed he is "the best thing that ever happened to Puerto Rico," and that the problem is "bad Island leadership and with so much money wasted."

Democrats and Puerto Rico officials said money has been appropriated for hurricane relief, but only a fraction has actually been spent.

In her response, Cruz – who is now running for governor of Puerto Rico – said Trump "KNOWS HIS RESPONSE was innefficient at best. He can huff & puff all he wants but he cannot escape the death of 3,000 on his watch. SHAME ON YOU!"
