The super PAC backing New Jersey Gov. Chris Christie for president released a new ad on Monday that rips President Obama's foreign policy and Democratic presidential candidate Hillary Clinton.
"Hillary Clinton will be a third term of Barack Obama," Christie says in the beginning of the 30-second ad titled "Tested."
The ad created by America Leads goes on to say Mr. Obama's "failed" foreign policy has led to the rise of the Islamic State in Iraq and Syria (ISIS).
"Radical Islamic terrorism cannot continue," Christie says in a jab at the president, who has been criticized by Republicans for not using the same language to describe ISIS.
Christie then talks about being named U.S. attorney on the day before the 9/11 terrorist attacks.
"I've watched the loss and the suffering and the pain," he said. "My number one priority as a leader is to make sure that there isn't another generation of widows and orphans created because of a terrorist attack on the American homeland."
The ad is part of a $6.9 million buy for the Boston and New Hampshire TV markets and will air over the next seven to 10 days, according to a spokesman for America Leads.
It's coming out just over a month away before the primary season kicks off with the Iowa caucuses on Feb. 1 and the New Hampshire primary on Feb. 9.
The most recent CBS News battleground tracker poll found Christie in fourth place with 11 percent support in New Hampshire, trailing behind Donald Trump, Ted Cruz and Marco Rubio.
