Rep. Barbara Comstock, R-Va., announced her endorsement of Sen. Marco Rubio's presidential campaign Wednesday, one day after the fifth GOP debate in Las Vegas.

"Marco Rubio represents a strong, new generation of leadership who can turn the page from the failed Obama and Clinton policies, focus on the future, rejuvenate our economy, and create a strong, safe and prosperous America," Comstock said in the statement.
