House Democratic Caucus Chairman John Larson announced the elevation of Lee Slater, the Connecticut Democrat’s legislative director, to chief of staff today.

Slater will replace outgoing Chief of Staff Shelley Rubino. Slater has been with Larson since 2008 and served as his legislative director since 2009. He previously worked for Rep. Jason Altmire (D-Pa.) and was an Army reservist who served in Iraq and Afghanistan.

“Since joining the Chairman’s staff, I have been honored to work with a highly professional and supportive team,” Slater said in a release. “Together we have served the first district of Connecticut and the nation to our utmost ability and I am now looking forward to continuing this work in my new capacity as Chief of Staff.”

David Sitcovsky, currently a senior legislative assistant, will take over as Larson’s legislative director. John Rossi will continue to serve as chief of staff for district operations, the release said.

Today’s staff announcements came after Rubino announced last week that she was hanging up her Congressional badge to join Airlines for America as its vice president of global government affairs next month.

Larson, the No. 4 Democrat, is in his second and final term as Caucus chairman.
