Cruz made the remark in a Sept. 13 statement on social media, which came as President Joe Biden celebrated the passage of the Inflation Reduction Act, which includes nearly $46 billion in new funding for IRS enforcement out of the $80 billion or so total funding boost to the tax agency.

"Every single Republican should commit to not funding Biden's army of IRS agents," Cruz said in the statement.

While Democrats have portrayed the Inflation Reduction Act as an anti-inflationary measure that would lower the cost of healthcare, prescription drugs, and energy, Republicans have argued it would lead to higher energy prices and aggressive IRS audits.
