Sen. Lindsey Graham on Friday said it's time for the U.S. to use "the threat of a credible military option" against North Korea.
The South Carolina Republican has had enough of the rogue nation after it launched another missile early Friday that whizzed over Japan.
The intermediate missile flew 2,300 miles, putting it in range of the U.S. territory of Guam, an island that North Korea has threatened previously.
Graham in August praised President Donald Trump for using the "right rhetoric" in challenging North Korea.
