WACO (January 31, 2012)--Heisman Trophy Robert Griffin III heads to Washington, D.C. on Wednesday at the invitation of President Barack Obama and his wife Michelle.

On Thursday Griffin will lead a prayer at the National Prayer Breakfast at the Hilton Washington International hotel.

Earlier this month, Griffin decided to pass on his final season of eligibility at Baylor to enter the NFL draft.

On Jan. 16, he flew to Arizona accompanied by his mother and fiancée to begin five weeks of intensive training at a sports performance facility.

The three will fly to Washington Wednesday where they’ll be joined by Griffin’s father who remained in Copperas Cove while his son trains.

From Washington, Griffin III heads to Indianapolis where he will take part in Super Bowl media events.

He hasn’t decided whether to attend the game Sunday, his parents said.

Griffin is projected to be one of the top picks in April's NFL draft.

He and Stanford's Andrew Luck, the Heisman runner-up, are likely to be the first two quarterbacks selected.

Griffin played 41 games during his record-setting career at Baylor, completing 800 of 1,192 passes (67 percent) for 10,366 yards with 78 touchdowns and 17 interceptions, along with 2,254 yards and 33 TDs rushing.

He completed 72 percent of his passes this year for 4,239 yards and 37 TDs.
