Republican Rep. Marjorie Taylor Greene of Georgia boos President Joe Biden during the State of the Union
  • Rep. Marjorie Taylor Green called Biden a "liar" after he accused the GOP of wanting to cut Medicare and Social Security.
  • GOP lawmakers had previously been floating cuts to those programs during debt limit negotiations.
  • But McCarthy said cuts to Medicare and Social Security are "off the table."

Republican Rep. Marjorie Taylor Greene joined fellow Republicans in shouting down President Joe Biden during the State of the Union, a raucous moment that underlines the tension on key economic issues.

"You lie, you lie," Greene shouted from the back of the House chamber. She was far from the only House Republican who was outraged at Biden's suggestion that the GOP would end Medicare or Social Security, massively popular federal programs.
