Mayor Murray bans official travel to North Carolina because of anti-gay law.

The (Washington DC's) city’s mayor, Democrat Muriel Bowser, has already banned city travel to North Carolina because of a new law that excludes LGBT people from protections against discrimination.

Several states are actively demonstrating their opposition to the law Mississippi passed on Tuesday which discriminates against the LGBT community.

Vermont, Washington state and New York‘s governors all banned official state-funded or sponsored travel to Mississippi on Tuesday.

North Carolina's Anti-LGBT Law Has Cost the State More Than $560 Million So Far: Sporting events move elsewhere: $245.6 million. The first and largest loss was the NBA All-Star Game, which would have had a roughly $100 million economic impact in the Charlotte area. Next was the NCAA, which pulled seven national championship events from North Carolina, including the first and second rounds of the men's basketball tournament. NCAA losses include $16.1 million to the city of Greensboro and $2 million to Cary. The Atlantic Coast Conference removed its championship games from the state, including Charlotte's football final, which would have brought the city $32.4 million, and Durham's baseball tournament, representing $5.2 million in lost revenue. WRAL estimated that total losses resulting from ACC and NCAA cancellations were $90 million. But that's not all: The Central Intercollegiate Athletic Association announced in August that it would relocate 10 championships; its men's and women's basketball tournaments alone earned Charlotte $55.6 million in 2015.

Conventions cancel: $18.4 million. WRAL reports that Raleigh has lost nearly $9 million from numerous cancelled conventions, and Greensboro has lost $6 million from eight conferences that moved out of state. As of late April, Asheville had lost around $2 million in tourism revenue. Orange County will lose a projected $1.2 million of previously expected tourism. By early April, at least 13 conventions had pulled out of Charlotte, and a May 20 estimate by the Charlotte Regional Visitors Authority based on seven of these put the lost revenue at $227,000.

Creating and defending HB2 costs taxpayers: $267,500. The North Carolina government is racking up hundreds of thousands of dollars in bills to defend HB2, with more costs to come as legal battles over the law continue. As of July, the state had already spent $176,000 on court costs, and former Gov Pat McCrory (R) spent $7,500 of government funds on travel to defend the law on television. The bill was created in a "special session" that cost taxpayers $42,000, and the recent special session that failed to repeal HB2 cost another $42,000.

Major performances defect: $208,000. Ani DiFranco, Blue Man Group, Boston, Bruce Springsteen, Cirque du Soleil, Itzhak Perlman, Maroon 5, Nick Jonas, Pearl Jam and Ringo Starr all canceled North Carolina performances because of the law. It's hard to find definitive numbers for how much these cancellations cost the state, but Greensboro Coliseum and its vendors alone say they have lost at least $208,000 because of HB2-related cancellations.

Other losses are more difficult to quantify. Because of HB2, film companies A&E Studios, Turner Broadcasting and Lionsgate pulled planned future productions out of North Carolina. The Lionsgate production alone would have provided 100 jobs. Director Rob Reiner said he won't consider North Carolina for any future productions unless HB2 is repealed, and other film companies including 21st Century Fox say they'll reconsider future projects in the state.

Travel bans to North Carolina in effect in the United Kingdom, five US states and numerous cities are also costing the state money. Still more losses loom, including potentially $4.8 billion in annual federal funding, as the US Department of Justice has said that HB2 violates seven federal laws including Title IX of the Education Amendment, Title VII of the Civil Rights Act and the Violence Against Women Act. However, federal action is less likely under the Trump administration.
