Rodman says Obama not doing 's---' when it comes to North Korea

Dennis Rodman blasted President Obama on Thursday, saying he "can't do s---" when it comes to North Korea.

The former NBA star criticized Obama for not doing enough to release American Kenneth Bae, a tour operator who was sentenced to 15 years hard labor in North Korea for allegedly plotting to overthrow the government. The U.S. has called for his release.

Rodman told TMZ that he's going back to North Korea on August 1 to talk with President Kim Jong Un about releasing Bae.

"I'm gonna try and get the guy out," Rodman said. "It's gonna be difficult."

He added: "We got a black president [who] can't even go talk to [Jong Un] ... Obama can't do s---. I don't know why he won't go talk to him."

His tirade against the president continued with: "Obama? F--- him."

Rodman tweeted last week: "I'm calling on the Supreme Leader of North Korea or as I call him 'Kim', to do me a solid and cut Kenneth Bae loose."

He visited North Korea in February and sat with Kim for a basketball match. Afterward he said of the leader: “Guess what? I love him. He’s really awesome.”

The State Department did not endorse Rodman's visit, as the U.S. has not had formal diplomatic relations with North Korea since the end of the Korean War. The government is working through other channels to try to release Bae.

Rodman tells TMZ that despite his work: "I'm not a diplomat."
