President Trump chastised the Democratic presidential candidates after the end of their second round of primary debates Wednesday night.

In a pair of tweets, fired off just after midnight, the president warned that the economic prosperity during his administration will be lost if one of the Democrats is elected president in 2020.

"The people on the stage tonight, and last, were not those that will either Make America Great Again or Keep America Great! Our Country now is breaking records in almost every category, from Stock Market to Military to Unemployment. We have prosperity & success like never before," Trump said, adding, "It will soon be time to choose to keep and build upon that prosperity and success, or let it go. We are respected again all around the world. Keep it that way! I said I will never let you down, and I haven’t. We will only grow bigger, better and stronger TOGETHER!"

CNN hosted the latest round of debates in Detroit, with 10 candidates on stage per night. The first night featured candidates ganging up on Sens. Bernie Sanders and Elizabeth Warren. During the second night, front-runner Joe Biden appeared better prepared than he was in his first debate appearance, fending off political attacks on multiple fronts over his record on immigration, race, and crime.

Trump served as a target too. For instance, Hawaii Rep. Tulsi Gabbard said, “Donald Trump is not behaving like a patriot."

Although some candidates attacked former President Barack Obama's policies during the Wednesday debate, former Housing and Urban Development Secretary Julián Castro thanked his former boss for the strong economy, dismissing how Trump "always likes to take credit like he did this." He also said many pockets of Americans are still struggling, and said the "idea that America is doing just fine is wrong."
