President Donald Trump's administration is appealing a ruling blocking him from immediately firing Federal Reserve Gov. Lisa Cook as he seeks more control over the traditionally independent board. The notice of appeal was filed Wednesday, hours after U.S. District Judge Jia Cobb handed down the ruling. The White House insists the Republican president had the right to fire Cook over mortgage fraud allegations involving properties in Michigan and Georgia from before she joined the Fed. Cook's lawsuit denies the allegations and says the firing was unlawful. The case could soon reach the Supreme Court, which has allowed Trump to fire members of other independent agencies but suggested that power has limitations at the Fed.
