Tensions are rising across American academia as the Trump administration froze over $2 billion in multi-year grants and contracts at Harvard University after its leaders refused to make key policy changes the White House also is demanding of other elite US colleges.

The Trump administration froze $2.2 billion worth of federal money for Harvard University after the school said it would not cave to the White House’s orders to limit activism or political speech on campus.

The former US president says his successor has "done so much damage and so much destruction" in his first days in office.

Former President Joe Biden delivered his first public remarks since leaving office, criticizing the Trump administration, saying it has “taken a hatchet” to Social Security.
