Kamala Harris takes on a new role as she heads on her first overseas trip

The vice-president is helping lead Democrats' efforts to advance a set of voting rights bills after being seen by some as a floater' in the administration

When Kamala Harris leaves for her first overseas trip on Sunday, the US vice-president will be doing so with an expanded domestic portfolio.

Last week, Joe Biden announced in a speech that Harris would help lead Democrats' efforts to advance a set of voting rights bills, a top legislative priority for the party on an issue that disproportionately affects black and brown Americans. The president made the announcement during a speech in Oklahoma on Tuesday, where he marked the centennial anniversary of the Tulsa race massacre, which decimated a flourishing black community.
