WASHINGTON — New York Rep. Nita Lowey, the first female chair of the House Appropriations Committee, won’t seek re-election next year.

“After 31 years in the United States Congress, representing the people of Westchester, Rockland, Queens and the Bronx, I have decided not to seek re-election in 2020,” Lowey, 82, said in a statement.

Lowey made history in 2019 when she became the female leader of the powerful Appropriations Committee, where she hammered out spending packages and struck a bicameral, bipartisan deal to reopen the government in February without President Trump’s border wall funding.

In the 1990s, Lowey joined the committee that had long been dominated by males. She teamed up with Nancy Pelosi of California and Rosa DeLauro of Connecticut and the three friends were known as “DeLoSis” (pronounced like Pelosi). The trio fought for women’s health funding, including getting women included in clinical trials, DeLauro told Roll Call.

Lowey used her influence to appropriate funds for local issues such as the cleanup and protection of Long Island Sound and the Hudson River, homeland security assistance, funding the new Gov. Mario M. Cuomo Bridge and federal assistance for 9/11 and Superstorm Sandy victims.

Lowey said she’s not done yet and “will fight vigorously for House Democratic priorities as I negotiate spending bills for fiscal years 2020 and 2021.”

Afterward, “I look forward to more time with my husband Steve and our family, who have strongly supported my career in public service,” Lowey said.
