Education Act of 2006, would promote apprenticeships and similar initiatives. Kaine and Portman introduced similar legislation, the Educating Tomorrow's Workforce Act, in 2017. 2016 vice-presidential campaign Kaine endorsed Hillary Clinton for president in 2016 and campaigned actively for her in seven states during the primaries. He had been the subject of considerable speculation as a possible running mate for Clinton, with several news reports indicating that he was at or near the top of Clinton's list of people under consideration alongside figures such as Elizabeth Warren and Julian Castro. The New York Times reported that Clinton's husband, former president Bill Clinton, supported Kaine as his wife's vice-presidential selection, noting his domestic and national security résumé. On July 22, 2016, she announced Kaine would be her running mate in the election.
