IRS Commissioner John Koskinen has declined to testify in his own defense at a congressional hearing Tuesday, but insisted in a statement that his agency’s bungling of a subpoena doesn’t rise to the level of “treason, or high crimes and misdemeanors” needed for him to be impeached.

The Judiciary Committee hearing is being viewed by some House Republicans as the precursor to impeachment, with the House’s top investigator saying Mr. Koskinen defied a congressional order that demanded all of former IRS senior executive Lois G. Lerner’s emails be preserved as part of an investigation into tea party targeting.

But Mr. Koskinen, who said his schedule is too crowded for him to be able to appear on Tuesday, said the allegations against him are “unwarranted,” and no matter what, they don’t rise to the level of impeachment.
