“I have concerns about some of the language that is being used because I saw … I saw this myself in the late '70s in San Francisco,” Pelosi said, choking up and with tears forming in her eyes. “This kind of rhetoric is just, is really frightening and it created a climate in which we, violence took place and … I wish that we would all, again, curb our enthusiasm in some of the statements that are made.”

An uncharacteristically emotional Nancy Pelosi is warning Republicans — and other groups getting whipped up over the health care debate — not to incite unstable supporters who might repeat acts of violence that struck San Francisco in the 1970s.

"I think we all have to take action and responsibility for our words — we are a free country and this balance between freedom and safety is one that we, um, have to carefully balance," said Pelosi, who made no direct mention of Republicans.

She added: "You have to take responsibility for any incitement that [the speaker's words] may cause."

“Speaker Pelosi is right that the American people are upset, but it is her own words that continue to fuel voter frustration in America," Sessions said in a statement sent to POLITICO. "No longer content with criticizing concerned citizens for being ‘un-American,’ the Speaker is now likening genuine opposition to assassination. Such insulting rhetoric not only undermines the credibility of her office, but it underscores the desperate attempt by her party to divert attention away from a failing agenda."

Sessions, who raised eyebrows earlier this year by suggesting the House GOP minority needed to adapt the insurgent politics of the Taliban, added: "During one of the most important policy debates of our time, the American people have been completely abandoned by those elected representatives under her control. Voters are justifiably frustrated with Washington, and the Speaker's verbal assault on voters accomplishes nothing other than furthering her reputation for being wildly out of touch with the American people.”
