One of President Trump's longtime allies has openly criticized him for his approach to the Saudis during his first foreign trip abroad.

On Saturday, Stone tweeted a picture of Trump appearing to bend down as a civilian honor called the Collar of Abdulaziz al-Saud was placed around his neck by Saudi Arabia's King Salman.

Stone included the message, "Candidly this makes me want to puke #JaredsIdea."

According to CNN, his tweet indicated that "Trump accepted the award only at the suggestion of his son-in-law and senior adviser Jared Kushner, although he doesn't say why he made the assertion."

Meanwhile, Trump's receipt of the honor has been heavily scrutinized online for another reason; some are claiming that he "bowed" or "curtsied" to the Saudi king—a move for which he and others had criticized former President Obama in the past.

One person echoed the tweets of many, writing in response to Stone's post, "Yup, curtsied like a little girl to the Saudi king."

Meanwhile, others offered a different perspective, with someone else writing, "I despise Trump, but all he's doing here is reasonable protocol. I have no problem with it. But if it incites Trumpniks to puke, fine by me."

In regards to Trump's visit, Stone also tweeted, "Instead of meeting with the Saudis @realDonaldTrump should be demanding they pay for the attack on America on 9/11 which they financed."
