Senate Judiciary Chairman Lindsey Graham, R-SC, announced his plan to draft a letter to China’s government calling for the closure of China’s wet market, during an interview with “Fox & Friends” Tuesday.

“These are open air markets where they sell monkey, they sell bat. We think this whole thing started from a transmission from a bat to a human,” Graham explained.

He continued, “About the last three or four pandemics have come from the Chinese wet markets. I don’t think this came from a Chinese military lab, but these wet markets are gross, they’re just absolutely disgusting selling exotic animals that transmit viruses from animals to human beings.”

If the Chinese don’t comply, Graham said he will threaten to “change” the U.S. trade relationship with China.
