Boston City Councilor Sharon Durkan, a Wu loyalist, shared a selfie online announcing she won’t be at today’s council meeting because she’ll be “watching Mayor Wu as she testifies before Congress.”

Durkan did not answer her cell phone this morning. The mayor’s office did tell the Herald last night the city is spending $8,500 on “approximately 12 staff members” who have traveled with Wu to DC.

A source tells the Herald Durkan likely used her campaign funds to join the Wu team inside the Capitol.

Durkan posted a selfie on Instagram showing her inside a jet with the caption: “Good morning, Boston! (with a sun emoji) I won’t be at our weekly Council meeting because I’ll soon be in D.C., watching Mayor Wu as she testifies before Congress & also meeting with Senator Markey, and members of MA congressional delegation to fight against catastrophic funding cuts.”

The District 8 councilor has been in the news recently after attacking the Trump administration’s border czar Tom Homan, who vowed to “bring hell” to Boston over the city’s sanctuary-like Trust Act.

That’s why Mayor Michelle Wu is in Washington, D.C., today for a 10 a.m. congressional hearing on the city’s rocky relationship with ICE agents.
