Donald Trump has joined the popular video-sharing app TikTok, a platform he once tried to ban while in the White House, and posted from a UFC fight two days after he became the first former president and presumptive major party nominee in U.S. history to be found guilty on felony charges.

Some social media users are calling out celebrities for what they say is inaction in the face of a humanitarian crisis in Gaza — and they've taken to a "blockout" to pressure the stars to take a stand.
