A new diss track from one of hip-hop's biggest rap artists takes a swipe at President Obama.

Drake, whose recent "Hotline Bling" music video has scored over 400 million views on Youtube, called out the commander in chief for picking fellow rapper Kendrick Lamar over him in a recent interview.

"To do what you couldn't do. Tell Obama that my verses are like the whips that he in, they bulletproof" Drake raps in the track "Summer Sixteen," bragging that his lyrics are as formidable as Obama's armored presidential state car. Drake also takes aim at other artists he has quarreled with, including Meek Mill and Chris Brown.

In January, the president sat down for a Youtube Q&A and was asked who he thought, in a rap battle, would win between Drake and Lamar.

"Gotta go with Kendrick. I'm just saying. I think Drake is an outstanding entertainer, but Kendrick — his lyrics, his last album was outstanding. Best album, I think, last year."

Lamar's latest album, "To Pimp a Butterfly," received 11 Grammy nominations, including Best Album of the Year and Song of the Year for the track "Alright."

Obama told People magazine that his favorite song of 2015 was Lamar's "How Much a Dollar Cost."

When asked by a TMZ reporter what he thought about Obama's pick, Lamar said "That's great man."

Lamar visited President Obama in October at the White House, while he was in Washington, D.C. to perform with the National Symphony Orchestra at the Kennedy Center.

In January, Obama's senior adviser told Buzzfeed's "Another Round" podcast a little about the visit.

"You know what the president said to him?," she said, "[Because] he was a little nervous — bless his heart, he's really a very nice young man, and the president said, 'Can you believe that we're both sitting in this Oval Office?'"
