(CNN) In 2016, I was elected to Congress in a ruby red seat that no Democrat had won since 1933. As exciting as that night was, President Trump also won -- not only in my district, but in states all across America that traditionally went Democratic. Over the next two years, the Republicans controlled the House, the Senate and White House with an extremely partisan hand -- and they aggressively gutted everything from health care coverage to environmental protections.

Rep. Josh Gottheimer

Imagine if Democrats lose not only the White House, but also the House of Representatives, allowing a government completely controlled by Republicans ready to wreak even more partisan havoc on states like mine.

That's why I'm endorsing Mike Bloomberg for president. We need an experienced, proven leader who has big ideas, will fight to get things done, and knows how to work with -- and win votes from -- Democrats, Republicans and independents. We need a candidate at the top of the ticket who can win the White House and ensure we retain control of the House. That candidate is Mike.

First, as he demonstrated as an entrepreneur and a mayor, Mike is a proven problem solver. Bloomberg, who became an Eagle Scout at the age of 12, understood at an early age that you get things done only by working together. That approach helped him build one of the most successful businesses in America from scratch and drove his governing model in City Hall.
