Washington (CNN) Maryland Gov. Larry Hogan said Sunday that his state has received "hundreds of calls" from residents asking about the effectiveness of ingesting disinfectants to treat coronavirus after President Donald Trump dangerously suggested that it could be a possible treatment for the deadly virus.

"We had hundreds of calls in our hotline here in Maryland about people asking about injecting or ingesting these disinfectants, which is, you know, hard to imagine that people thought that that was serious. But what people actually were thinking about this, was this something you could do to protect yourself?" Hogan, a Republican, said in an interview on CBS.

Trump suggested during a White House coronavirus briefing on Thursday that ingesting disinfectants could possibly be used to treat people who have the virus, prompting cleaning product companies and state health officials to issue warnings about the dangers of doing so. The President also suggested sunlight might be a treatment.

Hogan, who has sparred with Trump at times during the crisis, said Sunday it's "always critically important ... for a leader to put out the facts and to be as open and honest and transparent as possible."

"And I think it's critical that the President of the United States, when people are really scared and in the middle of this worldwide pandemic, that in these press conferences that we really get the facts out there," he said. "And unfortunately, some of the messaging has not been great."
