Dr. Deborah Birx, who served as the White House coronavirus response coordinator while former President Donald Trump was still in office, opened up about her time working with the Trump administration during an exclusive interview with CBS News' Margaret Brennan on Sunday.Birx was often criticized for not pushing back enough on Trump's comments about the pandemic, and while she suggested her reactions could be misinterpreted -- like the time Trump asked her about whether COVID-19 could be treated with a bleach injection -- she did anticipate the gig would likely be the end of her federal career.
