(CNN) - Treasury Secretary Jack Lew requested - and has accepted - the resignation of the acting commissioner of the Internal Revenue Service in the wake of its handling of requests by conservative groups for tax-exempt status, President Barack Obama said Wednesday.
The "misconduct" detailed in a report about the IRS response to those requests is "inexcusable," he said.
"Americans have a right to be angry about it, and I am angry about it," he said.
He added his administration is working to enact "new safeguards to make sure that this kind of behavior cannot happen again."
