(CNN) - Former Maryland Lt. Gov. Kathleen Kennedy Townsend has become the third member of the Kennedy family to weigh in on the Democratic presidential race in the past 24 hours, issuing a statement Sunday in which she states her support for Hillary Clinton.
Her cousin Caroline Kennedy endorsed Barack Obama in an editorial in Sunday's New York Times. CNN has learned that her uncle, Massachusetts Sen. Ted Kennedy, will also endorse Obama.
"I respect Caroline and Teddy's decision, but I have made a different choice," said Kennedy Townsend.
"While I admire Sen. Obama greatly, I have known Hillary Clinton for over 25 years and have seen firsthand how she gets results. As a woman, leader and person of deep convictions, I believe Hillary Clinton would make the best possible choice for president."
She added that her brother Bobby and sister Kerry were also backing Clinton.
Kennedy Townsend is the oldest child of Robert F. Kennedy.
