Katie Pavlich said on "Outnumbered Overtime" that by opposing the tax bill en bloc, Democrats voted against the middle class.
Pavlich called Wednesday a "historic day for the president."
After being required to vote again on the tax bill after Sens. Bernie Sanders (I-Vt.) and Ron Wyden (D-Ore.) found violations of the Byrd Rule in the original bill, it passed both chambers by Wednesday afternoon.
Pavlich said the accomplishment was a "cherry on top" for President Donald Trump's first year.
She said that it was "astonishing" that the bill received no Democratic support.
"Every single Democrat voted against the middle class," she said.
