Hillary Clinton has no plans to be Barack Obama's vice president on a Democratic ticket for the White House, her campaign said Thursday, the dpa reported.
Phil Singer, a Clinton spokesman, said the former first lady was "not seeking the vice presidency," in a statement carried by CNN.
Clinton had previously said she was "open" to the idea and some of her supporters have launched a concerted effort to pressure Obama into putting her on a so-called "dream ticket."
Singer said the decision was Obama's to make, echoing comments by the newly-anointed Democratic nominee himself.
"I'm a big believer in making decisions well, not making them fast and not responding to pressure," Obama said in an interview with CNN.
Obama clinched the Democratic Party's nomination on Tuesday, becoming the first African American to lead a major US political party into the November general election.
Clinton is expected to formally suspend her campaign and endorse Obama at an event in Washington on Saturday.
