Markey floated several ideas on Twitter Monday, adding that "enough is enough."

"The epidemic of #gunviolence in our country is not preordained. It is preventable. It is time #GOP stops blocking #guncontrol legislation," he wrote in a tweet.

At least 58 people are dead and 500 others injured after gunfire broke out at a country music festival, authorities said earlier Monday, making it the deadliest mass shooting in U.S. history.

In the wake of the shooting, Markey said Congress could bolster background checks for buying a gun, including getting rid of a "loophole" that allows an individual to buy a gun through a private sale without a background check.

Let’s close the close the gun show loophole.

Let’s close the loophole that allows straw purchasers to buy guns and flood our streets with them.

Let's once again ban assault weapons. These are weapons of war and should be used in combat, not in our communities.

Any push to toughen gun control laws or broaden background checks faces an uphill battle in the GOP-controlled Congress. The Senate, controlled by Democrats in 2013, rejected a bipartisan background check proposal.

But Democratic senators are urging their colleagues to take action on new legislation after the Las Vegas shooting.

"None of this ends unless we do something to stop it," Sen.

Automatic weapons aren't needed to hunt deer or ducks; they're meant to kill people."

Markey also floated repealing a law that gives gun manufacturers broad protections from lawsuits tied to the "misuse" of a gun, or giving the Centers for Disease Control and Prevention funding to study gun violence like a "public health crisis."

Let’s study #gunviolence like the #publichealth crisis it is and fund the CDC’s budget. https://t.co/jbxUGhSbNS
