President Donald Trump said Wednesday that he would deny visas for foreign students who tried to come to the United States to attend Harvard University, his latest attack on the famous Ivy League Academy.

The government tried to revoke Harvard's ability to enroll at the end of last month, a move that was quickly blocked by a federal judge.

Trump said in his announcement Wednesday that Harvard did not provide the federal government with sufficient information about its foreign students.

"Harvard provided data on misconduct from just three students, and the data it provided was so inadequate that the Department of Homeland Security could not assess whether further action should be taken," Trump said.

Harvard University said it will fight to protect its international students.

"This is another illegal retaliation step taken by the government in violation of Harvard's First Amendment rights," a spokesman for the university said Wednesday night.

Trump has announced travel bans in 12 countries and restrictions on nine other countries, his promise.

The announcement said the president would “restrict access to foreign nationals seeking to enter the United States only or primarily attend Harvard study courses or Harvard-hosted exchange visitor programs.”

It added that the State Department will review existing foreign students under F, M or J visas to see if their visas should be revoked.

Trump and his administration attacked Harvard, saying that it has not been enough to fight anti-Semitism on campus during demonstrations against the Israel-Hamas war.

Harvard rejected Trump administration's request in April, which included the view of auditing student groups. In response, the federal government said it has frozen over $2 billion in federal grants.

Harvard said the government had previously tried to limit Harvard's ability to participate in foreign students by revoking its certification in the Student and Exchange Visitor Program. The government also attempts to ban Harvard from issuing F and J visas.

Harvard President Alan M. Garber responded in a May 23 letter that Harvard was retaliated for refusing to provide the Trump administration with illegal attempts to control it and its students.

"We condemn this illegal and unnecessary action," Farber said. "This has damaged the future of thousands of students and scholars across Harvard and warned others in universities and universities across the country that they have come to the United States to pursue education and realize their dreams."
