D.C. Council Chair Kwame Brown says Thomas needs to "seriously consider what's best for his family and constituents."
The District's Attorney General sued Thomas for allegedly misusing $300,000 in city funds.
Late last week, Thomas settled the lawsuit with the city, but the issue is far from over.
In a statement released late today, the chairman says Thomas should "seriously consider what's best for his family and constituents" but stops short of calling for the council member to step down, in contrast to council members David Catania and Mary Cheh, who have called for Thomas to resign.
Brown is the highest-ranking city lawmaker to officially comment on the settlement. He says, "no member of the council is above reproach" – and says, "the integrity of the D.C. government is at the forefront of any decision making."
On Friday, Thomas settled a civil lawsuit with the city and agreed to payback $300,000.
Thomas says his settlement does not include any admission of wrong-doing, but he’s still under investigation by federal officials.
