SAN FRANCISCO—San Francisco billionaire and philanthropist, Tom Steyer, announced his campaign for the 2020 presidential election on Tuesday, July 9 after denying his interest to run earlier this year.

Steyer joined the race a day after Eric Swalwell, the 37-year-old congressman and Democratic presidential candidate dropped from running. Steyer will replace him as the 23rd presidential candidate on an already full list of Democratic candidates.

According to StarTribune, the change in decision resulted in Steyer’s frustrations with the slow pace Democrats have taken to approaching Trump’s impeachment. He did not mention the president’s termination as the main goal of his campaign. He focused on issues such as keeping corporations out of politics, climate change, and the increasing opioid crisis.

In a tweet on Tuesday at around 6:09 a.m., Steyer stated: “When we come together, we can never be defeated. We can fix our democracy, and make sure it works for ALL Americans. We can elect new leaders at the local, state, and federal level. We can take back the Senate. But we can only do it together.”
