From a Trump spokesperson:

“President Trump, like all Americans, is entitled under the Constitution to an impartial judge and fair legal process. This motion lays out Judge Merchan’s significant conflicts. The Judge’s daughter stands to significantly financially benefit from a decision her father may make because of her her direct efforts with Joe Biden’s campaign. The motion also chronicles Judge’s Merchan’s conduct in a previous case when he pushed former Trump Organization CFO, Alan Weisselberg to cooperate against the Trump Corporation and President Trump. Judge Merchan also apparently made political contributions to Joe Biden and to causes such as ‘Stop Republicans.’ This case has no factual or legal merit, having been brought by a District Attorney who ran on a platform of ‘Get Trump,’ an impartial judge is vital to stop this travesty of justice.”
