The Washington Post’s Dana Milbank wrote that Republican presidential nominee Donald Trump has finally found a conspiracy he doesn’t like -- one that involves himself.

Milbank’s column noted reports that security experts say Russian hackers are behind the publication of thousands of Democratic National Committee emails on the night before the Democratic National Convention in Philadelphia, PA. The timing and sourcing of the email dump led media to question whether Russian officials were attempting to influence United States elections and whether Trump had any connections to Russian officials that may have played a role in the hack.

Trump has a well-documented history of invoking and encouraging conspiracy theories, claiming a “fix” was in when the FBI decided not to indict Democratic presidential nominee Hillary Clinton for her use of a private email server as secretary of state, suggesting President Barack Obama was sympathetic to terrorists and not an American citizen, and claiming the suicide of a Clinton aide was “very fishy.” Trump has also praised conspiracy theorist Alex Jones, who believes the government coordinated the 9/11 terrorist attacks and that a New World Order plans to exterminate 80 percent of the world.

In the July 26 article, Milbank wrote that despite engaging in theories that “President Obama is a Muslim born in Kenya, that Supreme Court Justice Antonin Scalia was murdered and that Ted Cruz’s father was involved in the JFK assassination,” Trump is “conspicuously incurious” about suggestions that he is working with Vladimir Putin to swing the U.S. presidential election. If Clinton were in Trump’s position, Milbank wrote, “it’s a safe bet that Trump would be demanding that Clinton release her tax returns to prove that she’s not beholden to Putin.” From the Milbank column:

Donald Trump never met a conspiracy theory he didn’t like — until now.

He has dabbled in, among other things, the notion that President Obama is a Muslim born in Kenya, that Supreme Court Justice Antonin Scalia was murdered and that Ted Cruz’s father was involved in the JFK assassination.

But on one topic, Trump is conspicuously incurious: the suggestion that he is complicit in a plan by Vladimir Putin to influence the U.S. election. Consider how Trump might react to the following fact pattern if the candidate involved weren’t “Donald Trump” but — let’s pick a name at random here — “Hillary Clinton”:

The candidate’s real estate empire, unable to borrow from most U.S. banks, gets capital from Russian sources. Such transfers couldn’t occur without Putin’s blessing.

[...]

If the Clinton campaign, and not the Trump campaign, were so extensively interwoven with Putin’s Russia, it’s a safe bet that Trump would be demanding that Clinton release her tax returns to prove that she’s not beholden to Putin — just as he demanded Obama release his birth certificate.

He would also very likely float allegations masquerading as questions by using the phrases “a lot of people have said” or “I’m hearing,” or “there’s something we don’t know about.” But Trump, I’m hearing, won’t be doing that in this case.
