Hillary Clinton joined a plethora of Democrats who have been pushing for new talks about gun control following the mass shooting in Las Vegas and condemned the Republican Party for being "totally sold to the gun lobby."

"I can't believe that one whole political party in the greatest country on earth is totally sold to the gun lobby," she said Wednesday to "Tonight Show" host Jimmy Fallon on NBC.

"The vast majority of Americans and the vast majority of gun owners know we need common sense laws," she said.

Following the mass shooting in Las Vegas on Sunday, which took the lives of at least 58 people and injured nearly 500 others, Democrats have renewed calls for harsher gun control restrictions.

The Trump administration has said that right after the shooting is not right to discuss new policy measures concerning gun control, but that didn't stop Sen. Dianne Feinstein, D-Calif., from introducing a bill Wednesday that would prohibit the sale and possession of "bump stocks," an accessory used by the gunman that enabled him to fire bullets more rapidly.

Clinton, who is in the middle of a book tour, also slammed Trump, her rival in the 2016 election. Clinton said she would not have been worried for the future of the country if another Republican had won.

"If I had lost to another Republican, someone I disagreed with but thought was temperamentally able to be president, I would be disappointed but I wouldn't be so worried about my country," she said.
