Some Starbucks customers are threatening to boycott the coffee giant after its CEO took a stand against President Donald Trump's executive order barring immigrants from seven majority-Muslim countries from entering the US.

On Sunday, Starbucks announced it planned to hire 10,000 refugees worldwide in the next five years.

"We are living in an unprecedented time, one in which we are witness to the conscience of our country, and the promise of the American Dream, being called into question," CEO Howard Schultz wrote in a letter to Starbucks employees about the plan.

While many customers were immediately supportive of Starbucks' actions on social media, others threatened to boycott after the letter's release.

"Upon hearing about your decision to hire 10000 refugees instead of Americans I will no longer spend any money at Starbucks," one such Facebook user wrote on Starbucks' page.

They want to hire refugees over Americans go 4 it! — Sandy (@sandra8301) January 30, 2017

Many said they were angry that Starbucks was hiring refugees instead of veterans. Starbucks, however, does have a program in place to support veterans and their families, hiring 8,000 veterans and military spouses since 2014.

#starbucks Why don't you hire the vets instead of refugees who might really ruin your business? #BoycottStarbucks — Marilynn Randall (@emjayr1942) January 30, 2017

Starbucks has no plans to end its program to hire veterans.

So instead of hiring 10,000 unemployed Americans or out of work vets @Starbucks will hire 10,000 refugees to spite @POTUS #BoycottStarbucks pic.twitter.com/cPbM1FvCwu — Νia☆ExtremeVetting☆ (@nia4_trump) January 30, 2017

Other users said the plan to give jobs to refugees would make it harder for Americans to get jobs. The 10,000 hires will be spread out over the 75 countries where the company does business.

Now they will hire people who don't belong here when AMERICAN high school/college students need a part time job. #BoycottStarbucks pic.twitter.com/17nip7wKmx — Hutch (@LawlessPirate) January 30, 2017

.@Starbucks will hire refugees over Americans. CEO Schultz proudly implements his #AmericaLast hiring priorities at Starbucks. #BuyDunkin — Small Biz for Trump (@SmallBiz4Trump) January 30, 2017

Some felt that Schultz was needlessly political in his plan to hire refugees.

Anyone else sick of @Starbucks CEO's pushing HIS political agenda through our coffee and down our throats?#BoycottStarbucks pic.twitter.com/nKZCzbZknA — McQ (@cultcommoncore) January 30, 2017

Schultz has long been vocal regarding his progressive beliefs as CEO of Starbucks. He endorsed Democrat Hillary Clinton for president in September, and he would have reportedly been Clinton's pick for secretary of labor had she won the election.

The movement to boycott Starbucks has already inspired a counter-protest — #BuyStarbucks, with supporters including actress Jessica Chastain.

This is not the first time there has been an online movement to boycott Starbucks.

In November, Twitter user Baked Alaska encouraged followers to visit a Starbucks location and tell the employees that their names are Trump in an effort to "normalize Trump" and the white-supremacist alt-right movement. When Starbucks introduced a green cup intended to promote unity in the week leading up to the election, social-media users accused the coffee chain of ""political brainwashing."
