The organization also reportedly saw a jump in online donations during the same period.

In the three years leading up to Trump’s election, the ACLU reportedly averaged between $3 million and $5 million in online donations per year.

“Until Trump, most of our support came from people who have been with us since we challenged Nixon,” Anthony Romero, the ACLU's executive director, told the Times.

“Now we’re kind of cool. Cool’s not a word generally associated with us,” Romero said.

The ACLU is a nonprofit organization whose stated mission is "to defend and preserve the individual rights and liberties guaranteed to every person in this country by the Constitution and laws of the United States.”

The organization, which was founded in 1920, has challenged Trump on a number of other issues since he took office, including the president's ban on travelers from Muslim-majority nations and his actions against allowing transgender people to serve in the military.

According to the Times, the ACLU has taken 170 "Trump-related legal actions" since he took office, including 83 lawsuits — more than during any other equivalent time in the organization's history.
