San Juan Mayor Carmen Yulin Cruz is attending a briefing with President Trump and first lady Melania Trump on Tuesday as part of their day-long visit to Puerto Rico to survey the damage from Hurricane Irma.

White House press secretary Sarah Sanders confirmed Cruz would be in attendance at the briefing, which included representatives from the U.S. military, FEMA, and the White House, as well as Puerto Rico's top officials. In photos taken before the briefing, Trump and Cruz can be seen shaking hands.

Cruz has been critical of Trump and the government's response to delivering aid after Hurricane Maria hit the island as a Category 4 storm late last month, knocking out power for all of Puerto Rico.

Since then, more than half of the island's residents lack access to drinking water, and food and fuel have been scarce.

In response to Cruz's comments, Trump unleashed a flurry of tweets about the San Juan mayor, and accused her of displaying "poor leadership."

Cruz told the Independent in an interview published Tuesday she hadn't received an invitation from the White House to attend any events with Trump, and said she wouldn't be upset if she didn't meet with him.

"I have mouths to feed and frankly, sir, you can insult me all you want. I can take it. But when you call my people ingrates—it's more than an utter insult, it is a sublime acknowledgement that you don't know our hearts," she told the Independent before Trump's arrival.

"I respect the office of the presidency of the United States, but I expect whoever holds it to respect the people I represent. … Talking about ingrates, to me that is an insult, it is indignity and perhaps I will accomplish more out on the streets saving lives."
