The main headings at Drudge:

MEMBER OF CONGRESS SHOT
SCALISE IN STABLE
‘WE WERE SITTING DUCKS’ TRAIL OF BLOOD
GUNMAN: ‘KILL AS MANY REPUBLICANS AS POSSIBLE’

And these are the minor ones:

Gunman opens fire at congressional baseball practice…
High-Powered Rifle; More than 50 shots fired…
‘Are Those Republicans or Democrats Out There?’
Kept unloading and reloading…
VIDEO…
SHOOTER NAMED…
“It’s time to Destroy Trump and Co.”
Capitol Police prevented massacre…
Security tightened at White House…
HILL ON EDGE…
Left-Wing TWITTER Celebrates…

And from that final story:

No sooner did news break that a gunman shot Rep. Steve Scalise (R-La.) were left-wing Twitter users celebrating the attack — in which two Capitol Police were also shot, as well as a congressional staffer, and possibly more.
