Biden aggressively prepares for debate while Trump cautions against excess preparation

According to multiple reports, President Trump has refrained from traditional debate prep and eschewed practice sessions. Trump indicated on Sunday that former New Jersey Governor Chris Christie and his attorney, Rudy Giuliani, helped him prep but it's unclear what exactly that entailed.

After beating former Secretary of State Hillary Clinton, who prepared extensively in 2016, Trump is suggesting he doesn't want to overdo it.

“Sometimes you can go too much in that stuff,” Trump said during a press briefing on Sunday.
