President Obama spoke at Kalamazoo Central's commencement ceremony in 2010.

On March 22, President Obama used Twitter to reach out to one of the students he met in Kalamazoo.

It's no secret that President Obama is a big basketball fan.

Obama publicly reveals his own brackets each year for the NCAA men's tournament. This year he has Michigan State University winning the tournament.

That love for basketball was shown again over the weekend.

Kalamazoo Central grad Devin Oliver met President Obama while the president was in Kalamazoo in 2010.

Today, Oliver is on the University of Dayton's basketball team.

President Obama tweeted at Dayton's basketball team to congratulate them after a big win on Saturday. Obama also addressed Oliver, wondering if they should play a pick-up game.

The White House Twitter account has tweeted over 13,000 times. Most of those tweets involve political issues and are done by staff. This tweet is signed "-bo" which indicates that President Obama wrote it himself.

Dayton's next game is Thursday night in Memphis against Stanford.
