Former Gov. Chris Christie is speaking out about his COVID-19 diagnosis and his decisions not to wear a face mask while meeting with President Donald Trump.

Christie attended several events in Washington, including a Rose Garden event to announce Amy Coney Barrett’s Supreme Court nomination and preparations for the president’s debate with Joe Biden. He was diagnosed with the coronavirus shortly after.

The former governor said in a statement, "I believed that when I entered the White House grounds, that I had entered a safe zone, due to the testing that I and many others underwent every day. I was wrong."

The statement continued, "I was wrong to not wear a mask at the Amy Coney Barrett announcement and I was wrong not to wear a mask at my multiple debate prep sessions with the president and the rest of the team."

Christie spent seven days in the ICU at Morristown Medical Center while receiving treatment for the virus.

The president, first lady Melania Trump and their son Barron Trump also came down with COVID-19, along with several members of the Trump administration.
