A sitting senator – a Republican - allegedly targeted by Lois Lerner at the IRS.
Lois Learner is at the center of the scandal - she's the top official accused of targeting political groups.
And now the chairman of the House Ways and Means Committee is accusing her of targeting Senator Chuck Grassley for increased IRS scrutiny as well. CNN's Joe Johns has more.
A White House lawyer has been subpoenaed over thousands of missing IRS emails. A congressional committee investigating the IRS scandal wants the attorney to appear before a hearing Tuesday.
It's one of several tough hearings on the scandal. The star witness at Monday's hearing is IRS commissioner John Koskinen.
The issue: thousands of missing emails belonging to Lois Lerner –the woman who headed the IRS division that targeted political groups applying for tax-exempt status.
Those emails could determine whether the order to target the tea party and other groups came from inside or outside the agency.
Republicans say the missing emails are further proof the agency is lying.
Democrats say this is just a witch hunt.
How likely is it the emails are really gone, accidentally, forever?
Tom Foreman has the answer.
Tempers flare on Capitol Hill.
During a House Oversight hearing about whether the IRS intentionally targeted conservative groups seeking tax exempt status, former IRS official Lois Lerner pleaded the fifth yet again.
The hearing turn ugly when the chairman of the committee, Republican Darrell Issa, tried to shut it down altogether, saying "Seeking the truth is the obligation of this committee, and I can see no point in going further."
That set off ranking Democrat Elijah Cummings.
As he stood up to leave, Cummings spoke into his mic: "Mr. Chairman? Mr. Chairman, I have a statement."
Issa ignored him and started to leave while Cummings continued. "Mr. Chairman, you cannot run a committee like this," says Cummings. "You just cannot do this.We're better than that as a country, we're better than that as a committee. I have asked for a few minutes..."
Issa muted Cummings' mic as he spoke. Issa returned to his seat and turned the mic back on, telling the rest of the chamber they were free to leave. “We've all adjourned, but the gentleman may ask his question,” Issa said.
