Raja Krishnamoorthi, Democratic candidate in Illinois' 8th congressional district, released a web video Wednesday featuring President Barack Obama.

In the video, Obama urges voters to vote for his "good friend" Krishnamoorthi. When Obama ran for the U.S. Senate, Krishnamoorthi served as his policy advisor. 

"When I ran for the U.S. Senate, Raja helped me develop ideas for building an economy that works for everyone," Obama says in the video. "Now Raja's plans will help small businesses grow, raise wages, and help families pay for college.
 
"The polls are open now, so don't waste a minute," Obama continued. "Vote Raja Krishnamoorthi for Congress."

Take a look:

Krishnamoorthi is going up against Republican Peter DiCianni in the 8th congressional district. The U.S. House seat for the Chicago west and northwest suburban district opened up for election after U.S. Rep. Tammy Duckworth opted to run against U.S. Sen. Mark Kirk.
