“We moved pretty promptly, but without any panic, and we are now in this location in another office building,” Sen. Blumenthal said.

Blumenthal said Wednesday’s actions were “not a protest, it’s an armed insurrection.”

“We are determined to show the American people… that these violent mobs attacking our democracy will not disrupt the transfer of power,” Blumenthal said.
