President Donald Trump shakes hands with Brazilian President Jair Bolsonaro before attending a working dinner at the Mar-a-Lago resort in Palm Beach, Florida, U.S., March 7, 2020.

Brazilian President Jair Bolsonaro, who met and dined with President Donald Trump at his Florida resort over the weekend, tested negative for the new coronavirus, his official Facebook page announced Friday.

His son, Eduardo Bolsonaro, who has shared updates about the Brazilian leader's coronavirus testing, also said that the results came back negative.

"Result of Jair Bolsonaro @jairbolsonaro for coronavirus it was NEGATIVE," Eduardo Bolsonaro said, a translation of his tweet shows.

That diagnosis came a day after Brazil revealed that Bolsonaro's press secretary, who also attended the Mar-a-Lago gathering, tested positive for the fast-spreading disease.

Trump said Thursday that he was "not concerned" about his exposure to that official, Fabio Wajngarten, and the White House said there were no plans for the president or Vice President Mike Pence, who was also at Mar-a-Lago, to get tested. Trump put Pence in charge of the U.S. response to the coronavirus.

But Bolsonaro did receive testing despite not showing any symptoms of the COVID-19 virus, according to a tweet from his son.

Earlier reports indicated that Bolsonaro had tested positive for the fast-spreading virus. Fox News initially reported that Bolsonaro had undergone multiple tests for the virus, the first of which came back positive. Other Brazilian outlets also reported that the first test showed Bolsonaro had contracted the coronavirus.

The president himself attacked the "fake news" on Twitter later Friday morning.

"DO NOT BELIEVE IN THE MEDIA FAKE NEWS!" a translation of Bolsonaro's tweet reads. "THEY ARE THEY WHO NEED YOU!"

The president's press office told CNBC in a statement that "the PR informed through social networks that the test was negative" for coronavirus. CNBC translated that statement from Portuguese.

Republican Sens. Rick Scott of Florida and Lindsey Graham of South Carolina said in statements Thursday that they had been in proximity to Wajngarten over the weekend. Both of those lawmakers said that they would quarantine themselves as a precautionary measure.

On Saturday, Wajngarten shared a photo on his Instagram page of himself standing directly next to Trump and near Pence in an ornate room. The Brazilian press aide is wearing a baseball cap emblazoned with the phrase "Make Brazil Great Again," a riff on Trump's campaign slogan.
