BALTIMORE (AP) — Baltimore’s former top prosecutor Marilyn Mosby has applied for a presidential pardon ahead of sentencing on her recent perjury and mortgage fraud convictions, according to The Baltimore Sun.

In a letter to President Joe Biden on Thursday, the Congressional Black Caucus expressed support for her cause, repeating claims made by Mosby and her attorneys that the prosecution was politically motivated, The Sun reported.

Mosby is set to be sentenced next week. She has asked for probation while prosecutors are seeking 20 months in prison.

“As a nation that leads by example, our justice system must not be weaponized to prevent progress toward a more perfect union,” wrote Rep. Steven Horsford, a Nevada Democrat who chairs the caucus.

The letter says Mosby submitted her pardon application on Wednesday. She recently appeared on MSNBC to argue her case.
