ORLANDO - Democratic state lawmakers want to pass emergency legislation requiring a ban on gun purchases by people on watch lists.

The Florida lawmakers called on Gov. Rick Scott on Wednesday to hold a special session on the legislation in the wake of the massacre of 49 people at an Orlando nightclub in what is the deadliest mass shooting in modern U.S. history.

The proposal would require the Florida Department of Law Enforcement to conduct an extensive background check on individuals who have been on watch lists before they can legally purchase or own firearms.

Gunman Omar Mateen was questioned three times in 2013 and 2014 by the FBI but the cases never went anywhere.

A special session could only be held if either the Republican governor wants one or Senate President Andy Gardiner and House Speaker Steve Crisafulli agree to hold one.

Neither is likely to happen since Scott has said the shooting in Orlando isn't about gun rights, and the speaker and president, both Republicans, said Tuesday they have no plans to call a special session to address gun laws.

Presumptive Republican nominee Donald Trump says he will be meeting with the National Rifle Association to discuss ways to block people on terrorism watch lists or no fly lists from buying guns.

Trump announced the meeting via a tweet Wednesday, without providing any details on the time or place. 

The NRA endorsed Trump last month. The nonprofit group advocates for gun rights.
