The Department of Justice asked a judge on Tuesday to sentence the woman who stole Ashley Biden’s diary to four to 10 months in prison, a tougher penalty than the six months of home confinement that the government had initially sought.

Prosecutors for the U.S. Attorney’s Office for the Southern District of New York said in a letter to a judge that Aimee Harris had “abused the administration of justice” by repeatedly providing inadequate excuses to the court that have caused her sentencing hearing to be rescheduled 12 times. They said the behavior warranted a harsher penalty.
