He is not currently an elected official, but former D.C. Council member Jack Evans still had a front-row seat for this weekend’s Lunar New Year festivities.

Evans resigned from the council Jan. 17, days before his colleagues were set to expel him for repeated ethics violations. On Monday, he filed paperwork with the D.C. Board of Elections to run again for his old seat.

A day earlier, the Democrat had raised eyebrows among some onlookers with an appearance at the annual Chinatown celebration in Ward 2, the center-city district he had represented for 29 years.

Evans marched Sunday alongside Mayor Muriel E. Bowser (D) and D.C. Council Chairman Phil Mendelson (D) near the front of the parade. Evans, who had been the council’s longest-serving member, later sat with current officeholders in the front row of a stage overlooking dance performances.

Mendelson, who had counted on Evans as an ally in recent years, told him it would be inappropriate for him to join other elected officials in presenting a ceremonial council resolution commemorating the Year of the Rat, a Mendelson spokeswoman said. Evans did not join them.

Lindsey Walton, the chairman’s spokeswoman, said Mendelson “doesn’t have any control over who shows up, but he thought it was inappropriate that Evans was walking with elected officials.”

Evans did not immediately return a call seeking comment.

A spokeswoman for Bowser, who has said Evans was reaping consequences for “very significant mistakes,” declined to comment on his parade appearance.

Raymond Lee, the parade commander, said he was not aware that Evans recently resigned and did not think much of his presence at the celebration.

“He just showed up on his own, as far as I know, and he always comes to the parade,” Lee said. “We’re not supposed to get involved in politics.”

Evans resigned after several ethics probes found that he used his public positions, including as chairman of the Washington Metropolitan Area Transit Authority board, to benefit private consulting clients who paid him hundreds of thousands of dollars.

He has also been the subject of a federal investigation that has involved subpoenas to the city government for records about Evans’s private clients and an FBI search of Evans’s Georgetown home. Evans has not been charged with a crime.

The council took a preliminary vote to oust him Dec. 3 and was set to finalize the vote last week. He would have been the first council member expelled by the council in city history.

The D.C. Board of Elections has scheduled a June 16 special election to fill Evans’s seat for the rest of his term, which runs through the end of the year. It will be held two weeks after the Democratic primary election for a four-year term in the Ward 2 seat, which is tantamount to the general election in a deep-blue city.

Evans filed to run in both the primary and the special election.
