"35 Repubs break ranks and vote to investigate the deadly riots of January 6th"

This was the headline on Fox news on the radio. There's so much wrong with this statement.
1. Deadly, really?
2. 35 repubs break ranks and vote for the investigation... why do the Dems NEVER break ranks. It's an evil agenda they are promoting, certainly not all Dems are evil. How do they keep every Dem member in line?
3. IF this was reversed, and the Repubs were investigating riots allegedly caused by the Dems, the Dems would hijack the hearing and turn it against the Repubs (like they hijacked the Jan 6th protest and turned it against any good that would come from it [e.g., like the Senate not certifying the electors until the voting fraud allegations were investigated]). Can't they turn any investigation against the Dems and show they colluded to hijack the 1/6 protests and led them into the capital, refused extra security for the capital, etc.? Certainly there's some smoking gun showing the Dem's culpability in the 1/6 "riot"...
