The Obama administration is trying to regain its footing after a tidal wave of scandals swept the administration last week.
White House senior adviser Dan Pfeiffer insisted on weekend news shows that the White House had no knowledge of the IRS's targeting of conservative groups.
"No. But don't take my word for it," Pfeiffer said. "Take the word of the independent inspector general who said that he found no evidence that there was any influence from anywhere outside of the IRS."
Republicans charged that intimidation is part of a pattern in the Obama White House.
"Given the trend, culture within the administration to cover things up and part of it has to do with the intimidation that the administration is using against some of its criticism -- culture of cover-ups and intimidation that is getting this administration in so much trouble," Sen. John Cornyn, R-Texas, said.
Meanwhile, Republicans continue to investigate the Obama administration over what led to last year's Sept. 11 attack on the U.S. Consulate in Benghazi, Libya, that killed Ambassador Chris Stevens and three other Americans.
Sen. Rand Paul, R-Ky., says former Secretary of State Hillary Clinton needs to take responsibility.
"I've done it in every state and every stop because I think it's pretty important that she accept blame for not providing security," Paul told CNN "State of the Union Host" Candy Crowley last week.
"She was asked repeatedly to provide security in Benghazi on several occasions, including direct cables, and she says she never read the cables on security. I find that inexcusable and a dereliction of duty," he continued.
"Whether it has political overtones or not, it really goes to the heart of who you are as secretary of state if you do not provide security for an embassy that's begging for it. That's absolutely a dereliction of duty, and she should have resigned and accepted blame for it."
Former IRS Deputy Commissioner Steven Miller will appear before the Senate Finance Committee on Tuesday to answer more questions.
