Trump's tweets Monday about the RNC, planned for Charlotte, come just two days after the North Carolina recorded its largest daily increase in positive cases yet. A draft of the bill, authored by Republican State Rep. John Torbett of Gaston and circulated last week by North Carolina Republican Party chairman Michael Whatley, calls for convention events in Charlotte to be held at full capacity, just as Trump had demanded from Cooper. The bill would require attendees to complete both pre-attendance and daily health surveys and have their temperatures taken prior to entry. Torbett's bill is unlikely to garner support among Democratic state lawmakers, who are concerned about reopening the state too soon and holding mass gatherings.
