A half-dozen words that both used in their convention speeches led Donald Trump Jr. Thursday to accuse President Obama of plagiarism.

“I’m honored that POTUS would plagiarize a line from my speech,” Junior tweeted. “Where’s the outrage.”

What the younger Trump told Republicans was: “We will not accept the current state of our country because it’s too hard to change. That’s not the America I know.”

What Obama told Democrats was that the GOP offered “no serious solutions to pressing problems, just the fanning of resentment and blame and anger and hate. And that is not the America I know.”

But Obama had used the same “America I know” phrase in 2010 and 2012.
