Sen. John McCain (R-Ariz.) discussed his Senate re-election plans tonight on "On The Record."

McCain just formally announced today that he is running for his sixth term in office to continue to serve the country and people of Arizona. He told Greta Van Susteren that it wasn't a difficult decision for him to run again. 

"The country and the world is in more turmoil than ever before," he said. "And that's just not my opinion. There are threats to us thanks to this failed presidency and the incredibly hands-off leading from behind foreign policy."

McCain said that the country is in "grave danger" and that there's a lot of work to be done still. 

Van Susteren asked McCain what he thinks about Secretary of State John Kerry's negotiating skills in terms of the nuclear deal agreement with Iran.

"John Kerry has had a series of failures whether it be trying to negotiate Bashar al-Assad's departure from Syria, or the Israeli-Palestinian peace process," McCain replied. "It was obvious to all of us who know him that he was desperate for some kind of an agreement. This agreement is not only flawed, but it's dangerous."

McCain explained that "Kerry was willing to make concessions, which obviously now [is] a very flawed treaty or certainly very questionable."

Van Susteren also asked McCain about his thoughts on both Sen. Rand Paul (R-Ky.) and Sen. Lindsey Graham (R-S.C.) announcing that they are seeking the Republican nomination for president of the United States. 

McCain said that he wishes them both well on their campaigns, but that he is going to support Graham.
