DONALD Trump’s ex-lawyer Michael Cohen will “state publicly all he knows” about the US president after the former fixer was jailed for three years on Wednesday.

A New York judge said that Cohen deserved a harsh punishment for crimes including tax evasion, lying to Congress and arranging illegal payments to silence women who posed a risk to Trump’s campaign for the White House.

Cohen had said his “blind loyalty” to Trump made him feel a duty to “cover up” the president’s “dirty deeds”.

The 52-year-old’s crimes included evading $1.4 million (£1.1m) in taxes and misleading Congress about his talks with Russians about a Trump skyscraper project in Moscow.

An adviser said after the case Cohen will “state publicly all he knows” about Trump after special counsel Robert Mueller completes his investigation.

Lanny Davis, who was previously a lawyer for Cohen, said his former client “continues to tell the truth about Donald Trump’s misconduct over the years” and that he will assist Cohen in testifying before any Congressional committee “interested in the search for truth and the difference between facts and lies”.

Cohen was ordered to hand himself in to start his sentence on March 6.
