Jared Kushner claims he never colluded with Russia. So what if he did? There is a long history of incoming administrations colluding with allies and adversaries. Well-known Democrat and legal scholar Alan Dershowitz begs his party to stop crying wolf.

Kushner is guilty of marrying Donald Trump’s daughter and helping him win the White House. That’s the real crime Democratic politicians are trying to nail him for.

Dershowitz, a former Harvard Law professor, joined Boston Herald Radio while Kushner was being grilled by lawmakers behind closed doors yesterday.

“Collusion is not a crime. There is no such crime as collusion,” Dershowitz told us on our “Morning Meeting” show.

“Ronald Reagan colluded with the Iranians prior to becoming president to postpone the release of the hostages so he would get credit for it,” he said. “Virtually every incoming administration colludes with some ally and, sometimes, some adversary.”

Kushner was before Senate Intelligence Committee investigators to answer questions about a meeting he, Donald Trump Jr. and former Trump campaign manager Paul Manafort had last summer with a Russian lawyer and others.

Reading from prepared remarks outside the White House without taking questions from reporters, Kushner said, “I did not collude, nor know of anyone else in the campaign who colluded, with any foreign government.”

The meeting reportedly was aimed at getting dirt on Hillary Clinton. Opposition research is as common in campaigns as kissing babies. Everyone does it.

Dershowitz is spot on when he argues that this is not a legal issue but a political one.

“The Democrats are crying wolf. … They are yelling, ‘crime, crime, criminal offense and treason.’ … Somehow if there were a crime committed, even though I am not predicting that, they would have no credibility because they keep yelling wolf.”

For the last six months, Dershowitz has been trying to draw the sharp distinction between “what is a crime and what is a political sin.”

He said the media are fueling the misconception. He claims the New York Times, which once welcomed his Op-Eds, is no longer interested in his views.

“The New York Times will have five Op-Eds on alleged crimes committed by the Trump administration. When I ask to write one Op-Ed showing maybe the leaders should understand there are no crimes committed, they would not even respond. They don’t want their readers to hear the other side of the issue,” Dershowitz said.

Stay tuned for Dershowitz’s new book, “Trumped up! How Criminalizing Politics Is Dangerous to Democracy,” due out next month. We can only hope that by then politicians in both parties will have recognized the difference between crime and politics, and will get back to work on issues that actually matter.
