Sen. Martin Heinrich of New Mexico called Mike Lee’s land-sale proposal “horsesh*t” and said “85% of the money from these sales would go to pay for tax cuts” for the wealthy.

The Senate parliamentarian advised on Monday that Lee's controversial proposal to sell millions of acres of public land violated the chamber's rules.

The Senate Parliamentarian said language inserted into President Donald Trump’s budget bill by Republican Sen. Mike Lee that would mandate three million acres of public land be sold at auction runs afoul of the Byrd Rule.
