Hillary Clinton has never been good at closing deals, Donald Trump campaign manager Kellyanne Conway asserted Sunday, especially when it comes to President Obama’s birth certificate.

“Nobody confuses Hillary Clinton with Mariano Rivera. She’s not a good closer. And she wasn’t on this issue at all,” Conway said in an interview on CBS. “Associates of Hillary Clinton started pushing this issue because Barack Obama came out of nowhere. They never expected him to rise in the polls, let alone beat her in her Democratic primary, where a vast majority of voters, [who] by the way were female and rejected her.”
