Boxer's fundraising team sent an invite to Fiorina's personal e-mail asking her to attend the campaign's May 25 event with President Barack ObamaBarack ObamaWATCH LIVE: Obama speaks at African American Museum opening Obama talks racial tension at African-American museum opening Trump in 2011: Clintons ‘have done so much’ for blacks MORE in San Francisco.

The invitation states, "With the June Primary upon us, Sen. Boxer needs to be prepared to face the 'fight of her life.' Your support is critical."

It offers prospective donors who raise $20,000 the chance of attending a 'private clutch,' presumably with Boxer and Obama.

Fiorina won't be able to make it, according to campaign spokeswoman Amy Thoma. "Sadly, she'll have to decline as she'll be out giving Boxer the [above] referenced 'fight of her life.'"

The Boxer camp confirmed the e-mail was authentic but noted it went to "thousands" of people.

Fiorina wasn't the only Republican on the list -- her campaign manager, Marty Wilson, got the invite last week.
