Videos emerged Sunday of Rep. Steve Cohen (D-Tenn.) joining a rap group onstage at a campaign event. 

"Give him the support because the town is under pressure," the group rapped as Cohen danced alongside. 

The Tennessee congressman is a well-known music lover and has appeared at the Congressional Blues Festival in Washington. 

But Cohen, who represents a majority African-American district that contains the city of Memphis, has also faced criticism from black politicians in his district in the past. 

In 2008, he ran in a racially-tinged primary against attorney Nikki Tinker, whose campaign was criticized for running harsh ads against Cohen suggesting he was tied to white supremacist groups. 

Then-Sen. Barack Obama endorsed Cohen in the race, which he handily won. Cohen faces a primary challenge this cycle from ex-Memphis Mayor Willie Herenton, who is also African-American.
