Kamala Harris is stepping up her media appearances with direct appeals to Black voters and other groups as she struggles to take on Donald Trump with just three weeks to go in the White House race.

On Tuesday Harris was interviewed by Charlamagne tha God, a radio host whose syndicated show is popular with young Black Americans. On Wednesday, Harris will sit down with Fox News presenter Bret Baier in her first appearance on Rupert Murdoch’s conservative cable channel, in a bid to reach centrists and anti-Trump Republicans.

The media blitz — which could also include a forthcoming interview on Joe Rogan’s controversial podcast — marks a gamble by Harris to reach a wider pool of voters amid concerns among top Democrats that she is losing momentum against Trump.
