More revelations are now surfacing in the IRS scandal, with one email showing that disgraced former IRS official Lois Lerner targeted Republican Sen. Charles Grassley (IA) for an internal audit.

After the agency admitted it had lost two years worth of Lerner's emails during the targeting of Tea Party groups, congressional investigators have now uncovered the emails, which were published late Wednesday by the House Ways and Means Committee.

The emails appear to show Lerner mistakenly received an invitation intended for Sen. Charles Grassley, R-Iowa, in 2012. 

The event organizer, whose name is not disclosed, apparently offered to pay for Grassley's wife to attend the event, which caught Lerner's attention. The December 2012 emails show that in response, Lerner suggested to an IRS colleague that the case be referred for an audit. 

"Looked like they were inappropriately offering to pay for his wife. Perhaps we should refer to Exam?" she wrote. 

Her colleague, though, pushed back on the idea, saying an offer to pay for his wife is "not prohibited on its face." There is no indication from the emails that Lerner pursued the issue any further. 

Republicans pointed to the exchange as yet another example of Lerner using her position in the Exempt Organizations unit to apply scrutiny to conservatives. 

Sean Hannity weighed the new information with Jay Sekulow and Cleta Mitchell, two attorneys who are representing dozens of conservative groups singled out by the IRS.

Mitchell said these emails are not surprising, likening the IRS scandal to an infomercial where they keep repeating "wait, there's more."

"Every time you think you've heard it all, you hear something new, something outrageous that they've done," said Mitchell, arguing that now four IRS commissioners have given false testimony to Congress.

As for the missing emails, said to be gone forever after a computer crash, Sekulow pointed out there were recipients and if the emails exist, "we're gonna find them."
