The Koch brothers' political network will hold a panel discussion on Monday with Treasury Secretary Steven Mnuchin and White House Legislative Director Marc Short as part of the group's push on tax reform.
The Koch network is pouring millions into its effort on tax reform, which it says "largely mirrored the principles the White House has already outlined."
An early victory: The Koch network opposed the Border Adjustment Tax, favored by Paul Ryan, which Republicans took off the table Thursday.
Why it matters: This is another signal that the best-funded conservative group is willing to throw its resources behind tax reform. The Kochs didn't support Trump during the campaign, but they're allies on this issue.
