Not Joe Biden, Jill Biden got 12 while Trump got 3.
From the article:
Investigations done by Senators Ron Johnson (R-WI) as well as Chuck Grassley (R-IA) into the failures of the
Secret Service (USSS) in light of the
Trump assassination attempt have revealed several glaring missteps from the
agency, including that an event for Jill Biden nearby to the Trump rally on July 13 had 12 "post-standing"
USSS agents while Trump's rally had just three.
According to investigations done by Johnson as well as Grassley's offices, as reported on by RealClearPolitics’ Susan Crabtree, the Secret Service did not coordinate communications with local law enforcement and there were only three “post standing” USSS agents at the Trump rally while there were 12 at an event for Jill Biden the same day.
