From Nine To Noon, 9:20 am today

US Vice President Kamala Harris is continuing to shore up her support to be the frontrunner on the Democratic presidential ticket after her boss Joe Biden announced his exit from the race.

More Democrat heavyweights threw their support behind her overnight - Senate majority leader Chuck Schumer and minority leader Hakeem Jeffries announced their endorsement, joining others including Nancy Pelosi, the Clintons and a raft of influential state governors.

The money is pouring in too - some US$150m has been pledged to Harris and the party since Joe Biden endorsed her to replace him. But how might Kamala Harris fight her campaign, should she become the nominee? And what do we know of her political history that might inform her style of presidency?
