After Donald Trump began fundraising off of his Oval Office address for his "Official Secure the Border Fund," someone secured the domain name -- and used it for an excellent cause.

Dave Levinthal, a reporter with the Center for Public Integrity, tweeted Tuesday that Trump was raising funds off of his address under "a fancy name for his campaign's joint fundraising committee with the RNC."

He teased Thursday night that, which takes its name from the president's "fund," had a very different message.

The site features a white background and simple black Times New Roman font -- and a message denouncing the president.

"Donald J. Trump is a racist, a demagogue, a swindler, and a puppet of foreign influence," the site reads. "He and his presidency are illegitimate, and his wall is nothing but a vanity project."

"The true border crisis is the unlawful and immoral policy of family separation," it added. "Please consider donating to KIND (Kids in Need of Defense)RAICES, and the Legal Aid Justice Center to ensure childrens' legal rights and interests are protected. A secure border is one that welcomes the most vulnerable with support and compassion."
