Actually, chalk this one up as a potential win as Ted Cruz threatens to subpoena Treasury officials over ♡bamaCare!!! subsidies:
According to The Hill, the 2016 GOP presidential hopeful made the threat after he had been told that a number of officials would not be available to testify, specifically Mark Mazur, an assistant secretary for tax policy; Emily McMahon, deputy assistant secretary for tax policy; and Cameron Arterton, deputy tax legislative counsel for tax policy.
“This refusal is unacceptable and interferes with Congress’ and this Committee’s obligation to ensure proper functioning of federal agencies and the federal rule making process,” Cruz wrote in a letter to Lew.
Cruz added that the officials should have to testify “regardless of any perceptions of poor timing by, or inconvenience to, the executive branch.”
