President Donald Trump says Harvard University will be stripped of its tax-exempt status — redoubling an extraordinary threat that the Ivy League school’s president is pushing back against.

U.S. President Donald Trump said on Friday his administration will revoke Harvard University's tax-exempt status, returning to a threat he issued against the Massachusetts school last month as part of his wider attack on elite universities.

The judge said the order against the law firm of Perkins Coie violated multiple provisions of the Constitution.

President Donald Trump has targeted several law firms with penalties, four of which sued to challenge his actions.

U.S. District Judge Beryl Howell's ruling was the first deciding the legal merits of any of the several directives Trump has aimed at law firms.

US President Donald Trump has issued an executive order calling for all federal funding to the Public Broadcasting Service (PBS) and National Public Radio (NPR) to be blocked. On Thursday evening, Trump alleged that both organisations have engaged with "biased and partisan news coverage".

The order instructs the Corporation for Public Broadcasting, which distributes funding to PBS and NPR stations, to "cease direct funding" to them.

One hundred days into Donald Trump’s presidency, many questions on tariffs remain for consumers. Trump first announced sweeping tariffs on dozens of countries at the beginning of April, days before pausing most of them for 90 days.
