MONTPELIER, VT. >> Vermont Gov. Peter Shumlin is banning all non-essential state travel to North Carolina in protest of a new state law preventing local governments from expanding protections for lesbian, gay, bisexual and transgender people.

The Democratic governor on Tuesday joined New York Gov. Andrew Cuomo in banning non-essential state travel by state workers. Extraordinary circumstances may be appealed to the administration secretary.

The North Carolina law requires transgender people to use public bathrooms that match their birth certificates. The law also makes clear local measures can't expand anti-discrimination protections for sexual orientation or gender identity.

Shumlin called North Carolina's law "an absolute disgrace" and hopes other states will join Vermont and New York in applying pressure on the state to repeal the law.
