President Donald Trump waves to reporters as he departs with first lady Melania Trump for his first presidential debate with Democratic presidential nominee Joe Biden in Cleveland, Ohio, on Sept. 29, 2020.
Donald Trump Jr. had been scheduled to appear in McAllen for a "get out the vote" lunch event Friday, alongside Trump adviser Kimberly Guilfoyle.
"As many of you know, President Trump has tested for COVID19 and both Kimberly and Donald Trump Jr have been in close proximity to President Trump, our First Lady, Ivanka Trump, and Hope Hicks," the Hidalgo County GOP wrote on Facebook on Friday.
"Kimberly Guilfoyle and Donald Trump Jr. will be in quarantine for the next couple of days until they test negative for COVID."
We will see Donald Trump Jr. in Hidalgo County before Election Day," the party said.
