Sen. Arlen Specter, D-Pa., used Twitter to comment on a call he made to Sen. Chuck Grassley, R-Iowa, the Washington publication The Hill reported.
"Called Senator Grassley to tell him to stop speading (sic) myths about health care reform and imaginary 'death panels,' Specter said on Twitter. "Had to leave a message -- for now. I will talk to him soon."
Grassley replied just under an hour later: "Specter got it all wrong that I ever used words 'death boards'. Even liberal press never accused me of that. So change ur (sic) last Tweet Arlen."
Grassley is the ranking member of the Senate Finance Committee and is lead negotiator on healthcare reform for the GOP. He has clashed with Democrats over end-of-life provisions in the bill.
The Hill reported Grassley said a provision of the bill would create a government "death panel" to decide end-of-life issues. Such decisions "ought to be done within the family. We should not have a government program that determines if you're going to pull the plug on Grandma," Grassley said.
