Donald Trump isn't about to let anyone talk trash about his Miss Universe organization.

Earlier this week, Miss USA contestant Sheena Monnin resigned from her post as Miss Pennsylvania, alleging that Sunday's competition was rigged. On Wednesday, an outraged Trump spoke to Good Morning America about the beauty queen's "absolutely ridiculous" claims.

"I think that, frankly, she should apologize, but we will be bringing a lawsuit against her," he said. "She lost and if you look at her compared to the people who were in the top 15, you would understand why she's not in the top 15. It's a very, very sad situation."
