(CNN) - Hillary Clinton herself directly raised the issue of serving as Barack Obama's running mate in a conference call with New York lawmakers earlier Tuesday, a source who was on the call tells CNN's Candy Crowley.
According to the source, Clinton told those on the call that if asked by Obama, she would be interested in serving as his running mate. That comment was not in response to a particular question.
The Clinton campaign maintains the New York senator merely said she would do whatever is in the party's best interest, and that her comments Tuesday are no different than what she has been saying for weeks.
The source also said all the lawmakers on the call thought that Clinton needed to be on the ticket.
Rep. Nydia Velazquez, one of the call's participants, told CNN that she expressed on the call that Clinton needed to be on the ticket in order for Latino voters to cast ballots for Barack Obama.
"I expressed to her how the Latino community felt so strongly about her leadership and how she became a champion for Latinos, in fact a Latino leader in the eyes of so many Latinos," Velazquez said.
"I said to her at that I felt and I hear from many Latinos that there is a problem regarding Obama connecting to them and talking to them and I mentioned that also the same is true with blue collar workers and the women sector and so I say if we really want to win we need to have a ticket that can bring people together that can unify the party," she also said.
The representatives on the call included Reps. Charlie Rangel, Joseph Crowley, Steve Israel, Nydia Velazquez, Nita Lowey, Gregory Meeks, Eliot Engel, Jose Serrano, and Brian Higgins.
