The Colorado Senate convened on March 21, 2025, to address the appointment of a new senator for District 17 following the resignation of Sonia Hawkes Lewis. The meeting began with a roll call confirming a quorum of 33 members present, with one absence and one vacancy.

The primary focus of the session was the certification of Mary Kate Wallace as the new senator for District 17. Secretary of State Jenna Griswold presented the official certification, confirming that Wallace was appointed by the Democratic vacancy committee. Following this, Majority Leader Rodriguez moved to establish a committee on credentials to review the nomination, which was approved without objection.

After the committee's report was read and adopted, Chief Justice Marquez administered the oath of office to Wallace, officially welcoming her to the Senate. The session concluded with a brief recess for photographs and congratulations for the newly appointed senator.

This meeting marks a significant transition in the Colorado Senate, as Wallace steps into her role, representing the interests of District 17.
