Hillary Clinton attended a private fundraiser at the Park Hill home of Gov. John Hickenlooper and first lady Robin Hickenlooper on Thursday afternoon.

Her campaign would release no details to the press in advance.

The appearance was her first trip to Colorado since losing by nearly 20 percentage points to Sen. Bernie Sanders on March 1.

Clinton, however, is still in a close race for the state’s 78 delegates, because most of the state’s 12 superdelegates to the nominating convention support her.

The top donor level for the fundraiser is $27,000 in bundled contributions, according to an invitation obtained by The Denver Post. That level includes a special reception and photo with the Democratic candidate, as well as an invitation to the campaign’s finance summit April 20 in New York.

Those deemed “co-hosts” were expected to raise $10,000 in bundled contributions. A $1,000 contribution entitled a donor “preferred viewing” Thursday, while the minimum price to attend is $500 a person.

The maximum allowable contribution by an individual to a candidate’s committee is $2,700.

Thursday held a busy campaign afternoon for the Clinton family. While the candidate met with donors in Denver and Bexley, Ohio, her daughter attended events in San Antonio, Dallas and El Paso, Texas.

Bill Clinton campaigned for his wife in Philadelphia and Scranton, Pa., according to the campaign schedule.
