The President of the United States has five powers:
Commander in Chief - lead the troops and care for the veterans
Head of State - negotiate treaties, establish embassies and seek the peace
Make federal appointments - ambassadors, judges, etc.
Approve or reject legislation
He also has what President Teddy Roosevelt called a "bully" pulpit - an opportunity to occasionally address the American people on national affairs.
President Obama has spent the first six years of his presidency sitting on the "bully" pulpit, pushing for a legislative agenda. That's the job of the leaders of the House and Senate. If he had been attending to the duties of his office, he would have had the time and attention to devote to the issues that are now scandals. He would have attended the issues of veterans, ambassadors and IRS intrusions.
