WASHINGTON (AP) - President Barack Obama says the Internal Revenue Service's targeting of conservative groups is "outrageous" and anyone involved needs to be "held fully accountable."
Obama says at a news conference with British Prime Minister David Cameron that people are "properly concerned" about the IRS's targeting of conservative political groups. The president says he first learned of it when news reports broke on Friday.
Obama says he has "no patience for it" and will not tolerate a specific targeting of groups.
The IRS has apologized for what it calls "inappropriate" targeting of conservative political groups during the 2012 election to see if they were violating their tax-exempt status.
Sen. Max Baucus says the Senate Finance Committee will investigate the IRS targeting conservative political groups, joining a growing list of congressional panels looking into the matter.
The Finance Committee would be the first in the Democratic-controlled Senate to announce an investigation. The Montana Democrat is the panel's chairman.
In the House, the Ways and Means Committee and the Oversight and Government Reform Committee, also are investigating.
On Friday, the IRS apologized for scrutinizing the tax-exempt status of groups with conservative titles such as "Tea Party" or "Patriot" in their applications. An upcoming inspector general's report obtained by The Associated Press says IRS supervisors knew about the targeting as early as 2011.
