A video with hundreds of thousands of views appears to show people interrupting Ron DeSantis with chants of "We want Trump." But the clip has been altered; the original footage of the Republican Florida governor does feature heckling and booing, but not cheering for former US president Donald Trump.
The footage appears to show a CNN segment depicting DeSantis, who is challenging Trump for the 2024 Republican presidential nomination, pausing as hecklers in Jacksonville, Florida shout "We want Trump." The lower third says: "DESANTIS HECKLED IN JACKSONVILLE."
But the video has been altered to add the pro-Trump chant.
"It's fake," Bryan Griffin, the DeSantis campaign's press secretary, told AFP in a September 6 email.
Authentic footage from the Jacksonville event -- a vigil for three people killed August 26 in what officials said was a racially motivated shooting at a discount store -- does not show the crowd drowning out DeSantis with pro-Trump chants. Rather, it captures them heckling and booing the Republican as he began to speak.
The original, unaltered August 27 CNN segment featured a different chyron saying: "DESANTIS HECKLED AT JACKSONVILLE SHOOTING VIGIL."
The footage, credited to local TV station WJXT, does not include any pro-Trump chants. Videos with such cheering are "fabricated with an audio track and chyron," said CNN spokesperson Bridget Leininger in a September 6 email.
As governor, DeSantis signed legislation allowing Floridians to carry concealed firearms without a permit. He has also faced criticism for supporting guidelines dictating how Black history should be taught in schools.
