Activists have accosted Sen. Kyrsten Sinema, D-Ariz., at an airport and on her way to the bathroom. They also plan to follow her at the Boston Marathon Monday, pressuring her to support President Biden’s $3.5 trillion reconciliation bill, the Build Back Better Act.

Activists from the Green New Deal Network, a coalition of 15 organizations, plan on “bird-dogging” Sinema during the marathon, the organization announced in a press release, according to The Boston Globe.

Last week, video emerged showing Green New Deal Network Chief of Staff Kunoor Ojha accosting Sinema at Reagan National Airport in Washington, D.C., pressuring her to support the Build Back Better Act.
