Rihanna was tipped off by Washington Post White House bureau chief Philip Rucker.
“(Neither) me nor my people would ever be at or around one of those tragic rallies. Thanks for the heads up Philip (sic)!” she tweeted her reply to Rucker.
The development comes after Rihanna endorsed Florida Democratic gubernatorial candidate Andrew Gillum on Instagram.
Last week, Pharrell Williams sent a cease-and-desist notice to Trump after his popular track “Happy” was played at the US president’s political rally, the same day of the Pittsburgh synagogue shooting.
Other artistes who have forbidden the POTUS to using their music include Neil Young, Adele, Elton John, the Rolling Stones, Queen, George Harrison, Luciano Pavarotti, Steven Tyler and Prince.
