To a fault, President Trump values loyalty. So it isn’t surprising he demanded to know the identity of the whistleblower who exposed the Ukraine scandal. It is, however, irresponsible.

It would be just as irresponsible for House Democrats to allow the whistleblower to give up his anonymity and testify before the House Intelligence Committee, as Chairman Adam Schiff suggested last week. Whoever this person is, he or she should remain just that: an unidentified “whoever” that stays out of the spotlight.
