Google honored Fred Korematsu on Monday in its daily Doodle in celebration of what would have been his 98th birthday.

It isn't a milestone year, but the homage may just be a reference to Donald Trump's "Muslim ban," which put a 120-day halt on the entry to the U.S. of any refugees, a 90-day halt for all citizens of seven Muslim-majority countries, and an indefinite halt on all refugees from Syria.

Korematsu was an American civil rights activist who fought against Japanese internment during World War II.

Back in 1942, he, along with thousands of other Japanese-Americans, was forced to leave his home under an executive order by President Franklin D. Roosevelt.

Following Japan's bombing of Pearl Harbor, the president demanded law enforcement to identify and move Japanese-Americans into designated military zones. The issue was brought to the U.S. Supreme Court in 1944 in the case Korematsu v. United States.

Business Insider's Steve Kovach referred to the move as a "sub-doodle," in reference to the popular sub-tweet.

Perhaps Google has thrown shade before, but it's abundantly clear that one of the world's largest tech companies — that is headquartered in America and co-founded by an immigrant — is not holding back against Trump's executive order.

Google cofounder Sergey Brin was spotted protesting at San Francisco International Airport Saturday.

Google CEO Sundar Pichai sent an email to his staff late Friday, hours after the ban, sharing that the move affected at least 187 of his employees.

“It’s painful to see the personal cost of this executive order on our colleagues," Pichai wrote in an email, according to the Wall Street Journal.

Google also created a $2 million crisis fund that can be matched by up to $2 million in donations from employees. That would be the company's largest humanitarian campaign to date.
