Zawistowski said he has a four-inch thick binder of stuff they were asked to send, including speakers lists and printouts of every page from its website and Facebook page, every tweet.

He also refused to comply. Zawistowski applied for the status in June 2009 and received final confirmation on December 22, 2012.
In an appearance before the House Ways and Means Subcommittee on Oversight in March 2012, Shulman was asked about the controversy. Rep. Charles Boustany, R-Louisiana, asked if it was true the IRS was politically targeting conservative groups.
"Yes, I can give you assurances. We pride ourselves in being a non-political, non-partisan organization," he said. "There is absolutely no targeting. This is the kind of back and forth that happens when people apply for 501(c)(4) status."
Reaction to the IRS' admission was swift. House Majority Leader Eric Cantor announced Friday the House would investigate the matter, saying in a statement "the IRS cannot target or intimidate any individual or organization based on their political beliefs."
Senate Republican Leader Mitch McConnell called on the White House to conduct "a transparent, government-wide review" to ensure similar practices weren't being carried out at other agencies.
McConnell, who called an apology from the IRS insufficient, deemed the IRS tactics "political thuggery" with no place in American politics.
"Now more than ever we need to send a clear message to the Obama Administration that the First Amendment is non-negotiable, and that apologies after an election year are not an sufficient response to what we now know took place at the IRS," McConnell wrote in a statement.
The left-leaning American Civil Liberties Union also called out the IRS.
"Even the appearance of playing partisan politics with the tax code is about as constitutionally troubling as it gets," Michael Macleod-Ball, chief of staff at the ACLU's Washington legislative office, said in a statement. "With the recent push to grant federal agencies broad new powers to mandate donor disclosure for advocacy groups on both the left and the right, there must be clear checks in place to prevent this from ever happening again."
Tea Party groups were similarly incensed. The Tea Party Patriots, one of the nation's largest, rejected an IRS apology and insisted on resignation from the officials involved in the targeting.
"The IRS has demonstrated the most disturbing, illegal and outrageous abuse of government power," wrote Jenny Beth Martin, national coordinator for Tea Party Patriots, in a statement. "This deliberate targeting and harassment of tea party groups reaches a new low in illegal government activity and overreach."
Meanwhile, two Republicans on the House Oversight Committee, Chairman Darrell Issa and Rep. Jim Jordan, wrote in a joint statement, "The fact that Americans were targeted by the IRS because of their political beliefs is unconscionable. The Committee will aggressively follow up on the IG report and hold responsible officials accountable for this political retaliation."
The Democratic chairman of the Senate Permanent Subcommittee on Investigations, Sen. Carl Levin, also said an investigation into the matter was required.
Treasury Spokesman Anthony Coley said his department would "fully support the IRS Inspector General's review of this matter."
"The Treasury Department expects all individuals and organizations to be treated fairly by the IRS. Anything less is inappropriate and unacceptable," Coley said.
Jay Carney, President Barack Obama's press secretary, said Friday the IRS' actions were "inappropriate."
"We would fully expect the investigation to be thorough and for corrections to be made in a case like this," Carney continued. "And I believe the IRS has addressed that and has taken some action, and there's an investigation ongoing."
Of the 300 groups that were filed for further review, 130 have been approved, 180 are still in process and about 25 are under review, Lerner said.
Asked when the IRS began looking into complaints, Lerner said she could not give a time frame. Pressed further on when senior IRS officials became aware of the situation, Lerner said she "did not feel comfortable answering."
Lerner said they have implemented changes to prevent similar mistakes in the future. When asked if there has been disciplinary action, Lerner said "No." Attempting to clarify later, she said she meant to say she wouldn't comment on personnel issues.
