Sen. Sherrod Brown (D-OH) announced Thursday that he will not be joining the crowded field of Democrats running for president in 2020. His announcement comes after he weighed a 2020 bid and spent two months touring early voting states as part of a campaign to call attention to workers across the country.

"I will keep calling out Donald Trump and his phony populism,” Brown said in an initial statement. “I will keep fighting for all workers across the country. And I will do everything I can to elect a Democratic President and a Democratic Senate in 2020. The best place for me to make that fight is in the United States Senate."

He also explained his decision in a Twitter thread drawing attention to his tour to make “dignity of work a centerpiece of Democrats’ 2020 campaign.”

.@ConnieSchultz and I have spent the last few months traveling around the country to make dignity of work a centerpiece of Democrats’ 2020 campaign, and we are so grateful to everyone who has welcomed us into their communities and into their lives. — Sherrod Brown (@SherrodBrown) March 7, 2019

That’s why I’m confident it will continue to be a focus for Democrats in 2020. And I plan on making sure that happens I will keep calling out Donald Trump and his phony populism. — Sherrod Brown (@SherrodBrown) March 7, 2019
