Some top children's doctors are lending their voices to an effort to get McDonald's to stop marketing to children. They also want McDonald's restaurants kicked out of hospitals.
The advocacy group Corporate Accountability International sent letters to nearly two dozen restaurants that have McDonald's restaurants in their facilities.
Nearly two-thousand medical professionals across the country support the move, according to the organization.
McDonald's isn't the only fast foot restaurant that is sold in hospitals.
A spokeswoman for the advocacy group days they are focusing on McDonald's because "They profit most and they lead the way."
