Trump deserves 'fair chance' to challenge Manhattan prosecutor's subpoena for tax returns: filing

US President Donald Trump made a final push to keep his tax returns away from Manhattan's top prosecutor, as his lawyers said the US president deserves a "fair chance" to show a subpoena for the returns was overbroad and issued in bad faith.

Trump's lawyers made the argument on Thursday in a filing with the federal appeals court in Manhattan.

That court will hear oral arguments on Friday over whether Manhattan District Attorney Cyrus Vance can enforce a grand jury subpoena to Trump's accounting firm Mazars USA for eight years of his corporate and personal tax returns.
