Gregg Marshall accepts #IceBucketChallenge

After he and other staff members from the Wichita State Men's Basketball team were doused with ice cold water, he called out three people - former Shocker player Toure' Murray, former assistant basketball coach Chris Jans, and Charles Koch.

Melissa Colhmia, of Koch Industries, says Koch has accepted the challenge and will take it at 4 p.m. today.

The company says it will post the video to its Facebook page.
