Fire the IRS chief already, Mr. President

From the New York Post:

Why is IRS Commissioner John Koskinen still in office? A growing number of Capitol Hill Republicans want to know — and they have good reason to be troubled.

When he took over in 2013, Koskinen was supposed to “fix” the IRS — and in particular get to the bottom of the scandal in which the agency deliberately held up approvals for 75 conservative and Tea Party groups that had applied for legitimate tax exemptions.
