‘Hoax’ becomes fodder for blame-shifting?

I need to follow this stuff more carefully, I reckon.

Donald John Trump had been telling us that the Russian-meddling story was a “hoax,” a product of “fake news,” a figment of progressives’ and Democrats’ overactive imagination.

The president has yet to condemn the Russians for doing what intelligence agencies have concluded, which is that they sought to influence the 2016 presidential election through use of cyber activity.

Oh, but then comes this. He now blames the Obama administration for failing to stop the Russians in their tracks when President Obama was in office.

Which is it, Mr. President? Is the Russia story a made-up tale of intrigue meant to discredit your election as commander in chief? Or is it the real thing, something that now enables you to shift responsibility for ending it to your immediate predecessor as president of the United States?

Good grief, Mr. President? Keep it straight for us.
