One other person who followed him from a distance that day was the President of the United States.
On Monday, young Jack, his family and his friend, former Nebraska running back Rex Burkhead, visited President Obama in the Oval Office and talked for fifteen minutes. He received a signed football from the POTUS who told the littlest Cornhusker he was proud of him.
"I though it was awesome, " Hoffman said about his visit to the White House.
A photo released by the White House shows the pair chatting as Hoffman holds his souvenir. He was joined at the White House by his parents Andy and Bri and little sisters Ava and Reese.
"It was just such a great opportunity for us to visit him and raise national awareness for pediatric brain cancer," Hoffman’s father Andy said. "He talked about his commitment to research and science."
Hoffman was also joined at the White House by Burkhead, captain of the support network known as "Team Jack." The running back was drafted by the Cincinnati Bengals on Saturday.
