       Lawmakers have been meeting for days to hammer out a package to respond to the coronavirus outbreak. The $7.8 billion figure is in line with what sources told CNN over the weekend, a level far higher than the $2.5 billion White House request. Senate Minority Leader Chuck Schumer proposed $8.5 billion to deal with the outbreak last week.
