A "whistleblower" bill to protect government workers who report wrongdoing has constitutional problems and would interfere with legitimate discipline of employees, President Reagan said in announcing he will veto the measure.

The president said Wednesday he will exercise his "pocket veto" power of killing a bill by refusing to sign it while Congress is not in session.It had passed the House by 418-0 and the Senate by a unanimous voice vote.

The measure would have given major new protections to federal workers who expose fraud and mismanagement. Reagan said it would have allowed employees "who are not genuine whistleblowers" to manipulate the process to delay or avoid proper discipline.
