Christie not sure Trump will run again

New Jersey Governor Chris Christie has speculated President Donald Trump might not want to serve a second term.

Christie told NBC that four years is a long time, especially for someone who hasn't spent a lifetime in politics.

Christie thought those years may affect Trump "differently" than they would a seasoned politician.

Asked if he would support Trump for re-election, Christie said yes, but added that he is not sure a re-election campaign will happen.

Trump already has an active re-election campaign that is raising millions and often talks about serving eight years.

Christie ran for president but dropped out and endorsed Trump in February 2016 after a poor showing in New Hampshire.
