As the shooting was unfolding, Hillary Clinton was speaking to a crowd in Orlando about gun control.

“I’ll tell you what it also means standing up to the gun lobby. The gun lobby,” Clinton said. “It is time for us to say we are going to have comprehensive background checks, we are going to close the gun show loopholes. We are going to close the online gun loophole, we are going to close the Charleston loophole, and the immunity for the gun makers and sellers.”

The Democratic hopeful then took her reaction to Twitter.

I refuse to accept this as normal. We must take action to stop gun violence now. -H https://t.co/SkKglwQycb

Connecticut Sen. Richard Blumenthal, who served during the fatal Sandy Hook shooting, also reacted to the shooting.

In 30,000 tragic deaths every year — and now #SanBernardino — Congress is effectively complicit for its inaction.
