WATCH LIVE: Obama holds 'Google+ Hangout' to discuss State of the Union

President Obama will discuss his State of the Union address in a "virtual interview" Thursday on Google Plus at 4:50 p.m. ET.

The president will join the Google "Fireside Hangout" and field questions from selected participants about the policy proposals unveiled in his address to Congress on Tuesday.

Earlier Thursday, Obama spoke in Decatur, Ga., to unveil details of his plan to expand preschool programs. It was his second stop in a three-city tour to build support for his second-term agenda.

During the State of the Union, the president said he was committed to “working with states to make high-quality preschool available to every child in America.”

“In states that make it a priority to educate our youngest children, like Georgia or Oklahoma, studies show students grow up more likely to read and do math at grade level, graduate high school, hold a job, and form more stable families of their own,” Obama said. “So let’s do what works, and make sure none of our children start the race of life already behind. Let’s give our kids that chance.”

In Asheville, N.C., on Wednesday, Obama argued in favor of his administration's policies to boost American manufacturing at an auto parts plant.

“I believe in manufacturing,” Obama said at the plant. “I believe it makes our economy stronger.”

“Our middle class, when it's growing, when it's thriving … that's the American dream. That's what we have to fight for," he added.

Obama held a similar Hangout session following his address last January.

Vice President Biden also took to Google Plus last month to defend the White House's proposals on gun control.

During his online chat, Biden urged "a national dialogue" on gun violence.

"I don't view it as gun control, I view it as gun safety," Biden said, in his first-ever video chat on the social network.
