 As Republicans closed out their convention last night, another high profile Democratic lawmaker joined others in calling on President Biden to step down from the race. A top White House communication official dismissing one report that Biden could drop out as soon as this weekend, calling the report fan fiction. If Biden were to step aside, Vice President Kamala Harris is a leading contender to replace him on the ballot. A senior Biden administration official says President Biden has asked for polling on how Harris would fare against Trump.
