Marco Rubio is strongly mulling over a run for the Republican nomination for president in 2016.

 

ABC's 'This Week' caught up with Rubio in New Hampshire.

 

The Florida Senator says his decision will depend on where he can be most effective promoting conservative policies.

 

Rubio says if he does decide to run for president he won't run for re-election to the Senate.
