According to cbsenews.com, Mitt Romney stated that is was "an honor" to be considered to be President-elect Donald Trump's Secretary of State after the announcement that Rex Tillerson would be the next Secretary of State. The decision came after weeks of vetting various candidates for the job, including Romney, who met with Trump before Thanksgiving in New Jersey. Loyalists to Trump, including his own advisor, Kellyanna Conway, publicly discouraged Trump from choosing Romney for the position. There were reports that Trump faced clashes from his base over his possible decision to choose Romney, who railed against Trump during the GOP primary campaign. In a speech in March, Romney said, ""Let ,e put it plainly, if we Republicans choose Donald Trump as our nominee, the prospects for a safe and prosperous future are greatly diminished."
