Former D.C. Council chairman Kwame R. Brown will not be allowed to travel outside the Washington area for his nephew’s graduation ceremony next month, a federal judge ruled Wednesday.

Brown had hoped to attend the celebration in Raleigh, N.C., as both an uncle and a “surrogate father” for the son of his brother, Che Brown, according to court papers filed last week by Frederick D. Cooke, Brown’s attorney.

Che Brown himself will not be able to attend his son’s graduation the weekend of May 4. After pleading guilty to lying on loan documents, he was sentenced last month to 90 days in prison and was scheduled to begin serving his term last week.

In a one-sentence entry on the online court docket, U.S. District Judge Richard J. Leon denied Kwame Brown’s motion to travel, which was unopposed by the U.S. attorney’s office for D.C.

The former council member was sentenced last November to one day in custody and six months of home detention after he resigned from the council and pleaded guilty in a separate bank-fraud case.

Leon had denied Kwame Brown’s earlier request to loosen his detention restrictions by allowing him to continue his tradition of leading a bus trip for D.C. high school students to a college recruitment fair in North Carolina.
