Former GOP vice-presidential nominee and current House Budget Committee Chairman Paul Ryan (Wis.) is in the House.

Ryan was spotted standing on the Republican side of the chamber, next to Chief Deputy Whip Peter Roskam (R-Ill.) and Appropriations Committee Chairman Hal Rogers (R-Ky.). The three were chatting as various dignitaries entered the chamber.

As President Obama entered, Ryan (R-Wis.) stood at his seat on the Republican side of the House chamber.

He applauded along with other members, but also spent several minutes engaged in a what looked like a lively conversation with Roskam. The two could be seen from the House gallery making animated gestures and laughing heartily as Obama made his way down the center aisle.

While other potential 2016 White House contenders such as Sen. Marco Rubio (R-Fla.) and Sen. Rand Paul (R-Ky.) are taking on high-profile roles tonight, Ryan is laying low. Both Rubio and Paul are delivering formal rebuttals of Obama's speech. But Ryan, who delivered the GOP response last year, is not expected to give any remarks.
