Of course a president can initiate an investigation. The president is the boss of the ag. He is elected to be so. The ag is not elected. If the ag or doj lets criminals go the president has to get busy. In this case we are talking about theworst criminals in american political history. If he misuses the doj, the congress can impeach him.
He should have handed Sessions the comey report and file and asked, can ou move this to indictment. If he said no, he should have picked someone else. The comey report lists her crimes and national security violations. Then he should have ordered the foundation and uranium investigations expedited including the pay for access funds into the foundation and the Haiti scam.
Raise your expectations or you let these people ride off into the sunset and rip the heart out of the rule of law.
He is in a dangerous moment right now with the dems in charge of the House. They want him impeached and so far he is playing it smart. He is hands off and they can't accuse him of abuse of power, although they will try. This whole Russia collusion must pass completely from the scene and that will take awhile.
The House folks are already talking about abuse of power. When a weak link/some make believe questionable action surfaces, the House will demand all docs from the White House and all emails, etc etc to determine if Trump initiated anything.
It has been established that Huber is up to absolutely nothing. No players big or small has been interviewed by him or his staff so no one thinks he is accomplishing anything. It will be up to Barr to do this on his own and I'm sure Trump is hoping he will, but I guarantee there is no communication from the WH to the AG to initiate anything.
For what it's worth, I think the rank and file dems will demand an impeachment vote on abuse of power. They will find something they can twist to unbelievable heights and with the assist of the media will talk in hushed tones as to the gravity of the charges and something must be done to protect the constitution.
It will satisfy somewhat the dem voters and rank and file, but they will hound him until the day he leaves office. I know more than one lib and they really do believe he is walking evil and capable of any thing. Nothing will make these people believe he is not crooked.
