A federal judge on Monday dismissed US President Donald Trump's bid to block access to years of his personal and corporate tax returns, saying sitting presidents are not immune from criminal investigations.
In a 75-page ruling, US District Judge Victor Marrero rejected Trump's argument, saying such vast immunity would "operate to frustrate the administration of justice" by putting the president's personal and professional affairs off-limits.
