Senate Democrats told House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell on Tuesday that they should follow the lead of Republican presidential front-runner Donald Trump, who has indicated support for a Democratic plan to block people on the terrorist watch list from buying guns and explosives.

"Just two days ago, Donald Trump, the Republican front-runner for president, said anyone on terror watchlist should 'absolutely' not be allowed to buy guns," Democrats wrote in their letter to the two congressional leaders.

Senate Democrats want Ryan, R-Wis., and McConnell, R-Ky., to "quickly schedule votes on their legislation, the 'Denying Firearms and Explosives to Dangerous Terrorists Act of 2015.'"

Sen. Dianne Feinstein, D-Calif., first introduced the legislation in February, but Democrats begin promoting it again last week in response to the Paris terrorist attacks, which involved both guns and explosives.
