Donald Trump Jr. steps in it again (and again)

Story highlights

  • Donald Trump Jr. is active on social media
  • Not all of it draws positive attention

(CNN)Donald Trump Jr., the candidate's eldest child, emerged early on as one of his father's most ferocious advocates and polished surrogates.

But the shine is coming off after a series of damaging missteps -- the latest coming when he likened Syrian refugees to Skittles candy.
Trump Jr.'s lightly filtered Twitter account has at times appeared to be a clearinghouse for particularly unsavory media and commentary. On Tuesday, for instance, he retweeted a Breitbart story titled, "Europe's Rape Epidemic: Western Women Will Be Sacrificed At The Altar Of Mass Migration."
    Here are a few the son's latest stumbles:

    Compared Syrian refugees to Skittles

    "If I had a bowl of skittles and I told you just three would kill you. Would you take a handful? That's our Syrian refugee problem."
    At least, that's how Donald Jr., among others, would describe it.
    While many Trump supporters offered their support, the tweet provoked a broader backlash. Mars Candy eventually chimed in to distance themselves from the message.
    "Skittles are candy; refugees are people," the company said in a statement. "It's an inappropriate analogy. We respectfully refrain from further comment, as that could be misinterpreted as marketing."

    The moral question aside, Washington Post reporter Philip Bump pointed out a math problem.
    According to a recent Cato Institute report, the odds "that an American would be killed in a terrorist attack committed by a refugee was 1 in 3.64 billion a year."
    As Bump explains, the tweet could -- with the framing only slightly altered -- be interpreted as an argument for letting in more refugees.
    Still, the campaign insists Trump Jr. has been "a tremendous asset" all the way through.
    "Speaking the truth might upset those who would rather be politically correct than safe," Trump campaign spokesman Jason Miller told CNN in an email. "But the American people want a change, and only Donald Trump will do what's needed to protect us."

    Gave a new reason why Trump hasn't shared his taxes

    Donald Trump is on track to be the first modern presidential candidate withhold his tax information. The candidate and the campaign have for months said their reason for keeping a lid on the returns was an ongoing audit.
    But in an interview last week with the Pittsburgh Tribune-Review, Trump Jr. gave a very different explanation.
    The decision was made, he said, because Trump has "got a 12,000-page tax return that would create ... financial auditors out of every person in the country," and have them "asking questions that would distract from (his father's) main message."
    While there is no law preventing Trump from making the returns public, audit or not, Trump Jr.'s comment reflected what critics have been saying for months: that this is and always has been a political calculation.

    'Gas chamber' reference

    Complaining about media coverage is part of almost every campaign's playbook. References to "the gas chamber" are not.
    During an interview with Philadelphia-based conservative talk radio host Chris Stigall, he first described the press as the Clinton campaign's "number one surrogate."
    But then, this: "They've let her slide on every indiscrepancy (sic), on every lie, on every DNC game trying to get Bernie Sanders out of the thing. I mean, if Republicans were doing that, they'd be warming up the gas chamber right now. It's a very different system -- there's nothing fair about it."
    The campaign denied that Trump Jr. was making a Holocaust reference -- the Nazis used gas chambers as a tool of their World War II-era genocide -- and that the comment, a bit of hyperbole, was really about capital punishment more generally.
    "The liberal, dishonest media is so quick to attack one of the Trumps that they never let the truth get in the way of a good smear," Trump spokesman Jason Miller said in a statement.
    The Anti-Defamation League, a prominent Jewish advocacy group, was less sure.
    "Trivialization of the Holocaust and gas chambers is NEVER okay," they tweeted at Trump Jr.
    Clinton's campaign was especially biting, turning its response into an attack on Trump the candidate, with chairman John Podesta saying the son's language is "probably pretty consistent with the type of rhetoric he heard around the house growing up."

    Posting image of alt-right mascot 'Pepe the Frog' with Trump

    As Clinton was feeling the fallout from her "basket of deplorables" comment -- in which she initially suggested that half of Trump's supporters fit in a group composed of the "racist, sexist, homophobic, xenophobic, Islamaphobic, you name it" -- Trump Jr. made headlines with a controversial Instagram post.
    The photoshop composition featured his father leading a band of "deplorables," with political allies and the cartoon "Pepe the Frog" by his side. What Trump Jr. later said he did not know, was that "Pepe" has been appropriated as a mascot and preferred meme of the white supremacist alt-right movement.
    Asked about the post by ABC News on Sunday, Trump Jr. pleaded ignorance.
    "I've never even heard of Pepe the Frog," he said. "I had no idea there was any connotation there."

    Promotes anti-Clinton conspiracies

    His father's feed might get more attention, but Trump Jr. is just as active -- and sometimes more controversial.
    He often retweets the actor James Woods, who frequently shares suspect anti-Clinton media.
    "What is wrong with her?" Woods asked in a recent tweet, shared by Trump Jr., that quoted another user who wrote: "BREAKING!!! Collapsing Hillary Clinton Heavily Sedated as she responds to Donald Trump comment & #Chelsea !! #Valium"
    After a recent NBC News forum, Trump Jr. retweeted a post from right wing radio host John Cardillo, who was among the conspiracy theorists saying Clinton had been wearing an earpiece during the event.
    "Well look at that," Cardillo wrote. "Last night #CrookedHillary gets caught with #HillarysEarPiece. Today a new ear covering hairdo."

    Shared some choice thoughts on a 'herd of mothers'

    A look back at Trump Jr. in the pre-campaign days yielded some tasteless commentary on motherhood and a family employee.
    "Ever notice that if u get a herd of mothers together they aren't physically capable of talking about anything but birth pregnancy & diapers?" he asked in July 2011.
    About a year later, he offered this gem on the devotion of a particular employee, who Trump Jr. said skipped a family wedding to be at work.
    "At dinner w our greenskeeper who missed his sister's wedding 2 work (luv loyalty 2 us) "No big deal hopefully she'll have another someday";)" Trump Jr. tweeted.
