President Donald Trump on Monday lauded The Wall Street Journal opinion piece that suggests former President Barack Obama's role into the start and ongoing investigation into 2016 presidential election should be looked at more closely.

The Wall Street Journal asks, “WHERE IN THE WORLD WAS BARACK OBAMA?” A very good question! — Donald J. Trump (@realDonaldTrump) May 21, 2018

The Journal piece, written by James Freeman, assistant editor of newspaper's editorial page, asks:

"How and why exactly did leaders of U.S. intelligence and law enforcement agencies end up focusing on a domestic political campaign? . . .

"We can assume that the president was fairly well-informed about the law enforcement agencies reporting to him. Therefore, let's hear from him, in detail, the full history of how the government came to investigate the presidential campaign of the party out of power . . .

"If he doesn't know, then it would seem a public explanation is also in order — about his management, and about just how far the 'deep state' went without specific presidential approval."
