San Juan mayor Carmen Yulín Cruz has made a sartortial statement against President Trump by wearing a t-shirt with "nasty" emblazoned on it days after he used the word to describe her behavior towards him.

Cruz donned the black shirt during an interview with Spanish language television network Univision on Tuesday, ratcheting up tensions with the president as the pair weather the humanitarian crisis in Puerto Rico that has unfolded in the wake of Hurricane Maria.

On Saturday, Trump lashed out at Cruz, who has been mayor of the capital of Puerto Rico since 2013, after she said the Trump administration hadn't done enough to help the hurricane-ravaged U.S. island territory.

"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 Saturday morning about Cruz.

Trump deployed the same word against Hillary Clinton during the 2016 presidential election cycle.

This is not the first time Cruz has chosen to convey a political message through her fashion choices.

On Friday, Cruz wore a "Help us, we are dying" shirt during an appearance on CNN.
