State Sec. Marco Rubio is doubling down on his support for President Trump's decision to confront Iran, despite Republicans' losses in the midterms.
Rubio says Trump was elected to do the "hard things," arguing that previous presidents chose to leave the Iran threat for their successors to deal with.
"The most important thing a president can do for a country is to keep it safe," Rubio says, adding that Americans and future generations owe the president "a deep sense of gratitude."
