Chelsea Clinton goes global on the fundraising trail

Des Moines, Iowa (CNN)Chelsea Clinton will headline a fundraiser for her mother's campaign in London, England, on February 23, taking her now stepped up role on the campaign international.

Anna Wintour, editor in chief of American Vogue, will join Clinton in headlining the fundraiser, according to an invite obtained by CNN.
Tickets to the event run between $1,000 and $2,700 and the fundraiser will be hosted by Natalie Sara Massenet, the founder of the fashion website Net-a-Porter.
This will be the second fundraiser Chelsea Clinton will headline with Wintour. The duo headline an "afternoon tea" in New York on January 19.
The former first daughter has stepped up her role in Hillary Clinton's campaign this month, campaigning for her in Iowa and New Hampshire, and headlining over a dozen fundraisers across the country for her mother.
Also hitting the fundraising trail for Clinton: Secretary of Housing and Urban Development Julian Castro.
Castro, a rising star in the Democratic party and a widely speculated vice presidential option for Clinton, will headline a "coffee and conversation" fundraiser in Portland, Maine, on January 25, according to an invite.
This will be Castro's first time fundraising for Clinton. He endorsed the former secretary of state in October.
