Donald Trump is supporting controversial new legislation that would give people a nationwide right to carry concealed weapons – a measure that has been opposed by police chiefs across the country.
At the moment, concealed carry permits are issued by individual states. For example, a permit issued in Mississippi, where gun regulations are relaxed, does not allow a person to carry a weapon in California, where gun laws are much stricter.
But a bill that would mean each state has to recognise another state’s permit, in the same way it does driving licenses, recently passed the House of Representatives and a version of the legislation is now being considered by the Senate. In 2013, a similar bill failed by three votes.
