FILE - In this Jan. 6, 2015 file photo, Vice President Joe Biden administers the Senate oath to Sen. Joni Ernst R-Iowa, with her husband Gail Ernst and daughter Elizabeth, during a ceremonial re-enactment swearing-in ceremony in the Old Senate Chamber of Capitol Hill in Washington. Ernst says she turned down Donald Trump's request to run as his vice president in 2016 because of family concerns. Ernst made the claim in an affidavit in a divorce proceeding in October that was first reported by CityView, a Des Moines weekly newspaper. The filing was unsealed earlier this month after Ernst and her former husband of 25 years, Gail Ernst, settled their previously contentious divorce. (AP Photo/Jacquelyn Martin, File)
