In the e-mail, Clinton appeals to donors to help Meek meet his $100,000 fundraising goal for the quarter, which ends June 30.

From the e-mail:

"Kendrick has spent the last two decades faithfully serving the people of Florida, staying true to his core beliefs and giving everything he has to improving the lives of others. Now he's running against multiple opponents for the U.S. Senate.

"I know a little something about three-candidate races. I believe that Kendrick Meek is the best candidate, and that he's got a real shot at winning, but only if he gets our help now."

Meek, who is in a competitive Democratic primary against self-funder Jeff Greene, is in need of a boost.
