Conditions at the Park Southern Apartments were described as "disgusting" by Muriel Bowser during an appearance on The Kojo Nnamdi Show earlier this year.
The IRS has seized records from the Park Southern housing complex. The building in southeast D.C. has become a flashpoint in the mayor's race over alleged mismanagement.
According to residents who live at Park Southern, the building has fallen into disrepair and they accuse the building managers of financial mismanagement.
Earlier this year, the city fired the management company, sparking a legal battle.
The managers of the building are also backers of Democratic nominee for mayor Muriel Bowser, and at one point this spring she stepped in to try to resolve the issue. Her opponent in the race, David Catania, has criticized Bowser's handling of the issue and called for a council hearing. Bowser has defended her actions and said she believes the inspector general — not the council — should review the matter.
Now it appears federal authorities are taking their own look at the issue as city officials confirmed that IRS agents picked up a decades-worth of financial records from the building earlier this month.
