While his father was busy insisting that U.S.-Russia relations would survive this latest round of frost, Donald Trump Jr. was tweeting about fast food on college campuses.

Well, one campus in particular: Pittsburgh's Duquesne University, where LGBT students and their supporters say they fear the addition of a Chick-fil-A restaurant to a campus food court because of the company's "questionable history on civil rights and human rights."

Chick-fil-A came under fire a few years back after the company's owners expressed support for the biblical definition of the family unit and were found to have donated millions of dollars to "anti-LGBT organizations."

For these reasons, some of Duquesne University's LGBT students and their advocates voiced opposition to having one of the sandwich joints on campus, saying they feared it would undermine their efforts to make the dining hall a "safe space for all students."

Conservative media outlets were quick to seize on the story, calling it an example of liberal hysteria and the oversensitivity of millennials.

The president's eldest son got in on it too, writing in a Twitter post Thursday morning: "Luckily these students won't likely have to tackle issues more stressful than a yummy chicken sandwich in their lives...Oh Wait. #triggered."

Chick-fil-A has faced similar resistance in cities like Denver, where the city council debated the addition of a franchise to the Denver International Airport in 2015, with one member saying the deal was "really, truly a moral issue on the city" and another raising concerns about "corporate profits [being] used to fund and fuel discrimination," The Daily Beast reported at the time.

At Duquesne University, the Washington Times reported this week, student senator Niko Martini went so far as to file a petition with the student government asking the school to reconsider the inclusion of Chick-fil-A in its Options Food Court.

The paper says the student government did not adopt that resolution, but agreed to consider another measure vetting the views of the popular chicken sandwich shop.

In an email to PennLive, Bridget Fare, chief marketing and communications officer and associate vice president at the university, wrote: "A very small group of students have expressed concerns. The University has met with them, and we continued to reassure them that Duquesne does not tolerate discrimination of any kind. The overwhelming majority of feedback we have received has been positive, and Chick-fil-A Express will open on campus in the fall."

The university is a private Catholic institution with about 10,000 students and a campus near downtown Pittsburgh.

Meanwhile, it's unclear whether President Trump -- a prolific tweeter in his own right -- will weigh in on the controversy himself.
