The hashtag was the top trending phrase in the U.S. as of Tuesday morning, with nearly 50,000 tweets proclaiming what people thought former President Obama did better than Trump. 

While supporters of Obama boasted that he was better than Trump at "executive leadership," "marriage" and "being a human being," pro-Trump Twitter users also used the hashtag to suggest that Obama was better at "caving to terrorists" and "lying to the American people."

Trump sparked a political firestorm this week after tweeting Sunday that a group of four nonwhite lawmakers should "go back and help fix the totally broken and crime infested places from which they came."

The tweet was aimed at four freshman congresswomen: Democratic Reps. Ilhan OmarIlhan OmarSanders wants one-on-one fight with Biden Jayapal: 'We will end up with another Donald Trump' if the US doesn't elect a progressive Media's selective outrage exposed in McSally-Raju kerfuffle MORE (Minn.), Rashida TlaibRashida Harbi TlaibSanders wants one-on-one fight with Biden Democrats press Trump administration to stop DNA collection from detained migrants Jayapal: 'We will end up with another Donald Trump' if the US doesn't elect a progressive MORE (Mich.), Alexandria Ocasio-CortezAlexandria Ocasio-CortezBiden to go on Iowa tour with swing district lawmakers CNN cancels next week's Iowa town halls Sanders, Ocasio-Cortez hit back at JPMorgan CEO over comments on socialism: 'That's funny' MORE (N.Y.) and Ayanna PressleyAyanna PressleyPressley says she 'would welcome the opportunity' to educate DeVos after abortion, slavery comparison Massachusetts governor apologizes after calling Pressley speech a 'rant' Jayapal: 'We will end up with another Donald Trump' if the US doesn't elect a progressive MORE (Mass.).

Many Democrats and a handful of Republicans slammed the tweet as racist, and the House is expected to vote Tuesday on a resolution to condemn the president's comments. 

The president continued his criticism of the women on Tuesday, accusing them in a tweet of "spewing some of the most vile, hateful, and disgusting things ever said by a politician."
