Former Baltimore city state's attorney Marilyn Mosby is back in court Tuesday morning for a motions hearing leading up to her federal perjury trial in March.

Mosby is accused of lying about her financial hardship to avoid paying penalties in withdrawing $90,000 from her city retirement plan, then using that money to buy two vacation homes in Florida.

In a series of competing motions filed last week, both the federal government and Mosby's defense team asked the judge to exclude two of each other's expert witnesses.

the government wants to strike witnesses Jerome Schmitt and Eric Forster from testifying on Mosby's behalf.

Prosecutors say neither one has ever been qualified as an expert in a federal criminal trial.
