Palin endorses Trump; Rubio looks to gain ground in GOP race
Donald Trump has gotten the endorsement of Sarah Palin.
Palin, the former governor of Alaska and 2008 GOP vice presidential pick, says that with Trump as president, America would no longer apologize.
Marco Rubio is increasingly relying on a national strategy as he lowers expectations for February's primary contests.
Rubio is trying to break out of a pack of mainstream candidates, hoping Republicans eventually coalesce behind him as an alternative to Trump.
