Jesús 'Chuy' García endorses Brandon Johnson for Chicago mayor

CHICAGO (CBS) -- U.S. Rep. Jesus "Chuy" Garcia endorsed Cook County Commissioner Brandon Johnson in the race for Chicago mayor on Friday, giving his former rival a potentially big boost in his bid to defeat former Chicago Public Schools CEO Paul Vallas.

Despite entering the mayor's race as a perceived frontrunner, Garcia came in fourth place in the first round of voting on Feb. 28, with approximately 14% of the vote, while Johnson and Vallas took the top two spots. Mayor Lori Lightfoot finished third, losing her bid for re-election.

Garcia and Johnson, both prominent progressives, are now uniting in hopes of beating Vallas, who finished first on Feb. 28.

"Despite being opponents during February's election, Commissioner Johnson and I have shared priorities for our city, including public safety, quality education, affordable housing, community development, and ensuring Chicago remains a safe and welcoming city to immigrant communities. This moment symbolizes the strength our movements have together and our shared commitment to creating a better, safer, stronger Chicago," Garcia said in a statement.

Garcia's backing could help boost Johnson's support among Latino voters on the Southwest Side, as well as white liberal voters on the lakefront.

Early voting for the mayoral runoff election begins on Monday. Election Day is April 4.
