Marco Rubio Campaign Buys 'Several Million' Dollars' Worth Of Airtime For Ads in Early Primary States

— -- Get ready for it. The 2016 ad wars are coming soon to a television near you.

ABC News has learned Marco Rubio’s presidential campaign has pre-booked “several million” dollars worth of air time for advertisements in early primary and caucus states, becoming the first major ad buy of the 2016 presidential cycle.

A Rubio source tells ABC News the campaign has reserved air time in Iowa, New Hampshire, South Carolina and Nevada — all critical early states in the Republican nominating contest.

The ads won’t start running for some time, but Rubio, Florida's Republican senator, has locked in the time at lower rates by buying now.
