The White House has refused to release any images of Donald Trump signing a bill that made it easier for some people with a mental illness to buy guns.
Requests from US media outlets initially came after the US President signed the bill into law on 28 February last year, just a month after his inauguration.
But calls for their release have intensified in the wake of the Florida school shooting, which left 17 people dead, including 14 students.
On the day Mr Trump signed the bill, the National Rifle Association (NRA), America’s most powerful pro-gun pressure group, called it a “new era for law-abiding gun owners”.
The American Civil Liberties Union (ACLU), a group rarely on the side of the NRA when it comes to gun legislation, also supported Mr Trump’s repeal of the rule, insisting there was no evidence people affected “have a propensity for violence in general or gun violence in particular”.
