An IRS campaign to apply additional scrutiny to conservative groups went beyond targeting "Tea Party" and "patriot" groups to include those focused on government spending, the Constitution and several other broad areas.
The additional guidelines created by the agency were part of a timeline, obtained by Fox News, from the Treasury Inspector General for Tax Administration, which is looking into the controversial IRS practice. IRS officials apologized Friday for the scrutiny, but new information suggests senior leaders were apprised of the effort as early as 2011 despite public denials from the top.
Republican lawmakers have vowed to investigate and hold hearings, calling the revelations deeply troubling.
"The conclusion that the IRS came to is that they did have agents who were engaged in intimidation of political groups," Michigan Rep. Mike Rogers told "Fox News Sunday." "I don't care if you're a conservative, a liberal, a Democrat or a Republican, this should send a chill up your spine. It needs to have a full investigation.
