Republican lawmakers around the country are facing tough and often angry questions from constituents who are packing town hall meetings or showing up at their offices.

The pushback echoes the same raucous confrontations that Democrats faced in 2009, when tea party activists sprang into action to oppose what they saw as dangerous government overreach by President Barack Obama.
