WASHINGTON - Newark Mayor and U.S. Senate candidate Cory Booker joined other mayors to discuss reducing youth violence with President Barack Obama.

Newark Police Director Sam DeMaio joined Booker and U.S. Attorney General Eric Holder at the White House on Tuesday to talk about how the Obama administration can partner with cities.

"Today’s meetings underscored the vital importance of strategic coordination between the federal government and local leaders in crafting successful urban policies," Booker says. "We have serious challenges ahead of us, but I left the White House today feeling energized and optimistic thanks to the leadership of President Obama, Attorney General Holder, and the passionate mayors and police officials representing cities across America."

Booker is running against Republican Steve Lonegan to fill the vacancy caused by the death of U.S. Sen. Frank Lautenberg.
