President Trump on Sunday resumed his attacks on Democrats, targeting House Speaker Nancy Pelosi in a tweet.

“Speaking of failing badly, has anyone seen what is happening to Nancy Pelosi’s district in San Francisco,” Trump wrote. “It is not even recognizable lately. Something must be done before it is too late. The Dems should stop wasting time on the Witch Hunt Hoax and start focusing on our Country!”

The tweet comes a day after Trump lashed out at Rep. Elijah Cummings.

“Rep, Elijah Cummings has been a brutal bully, shouting and screaming at the great men & women of Border Patrol about conditions at the Southern Border, when actually his Baltimore district is FAR WORSE and more dangerous,” Trump wrote in a series of tweets. “His district is considered the Worst in the USA. As proven last week during a Congressional tour, the Border is clean, efficient & well run, just very crowded. Cumming District is a disgusting, rat and rodent infested mess. If he spent more time in Baltimore, maybe he could help clean up this very dangerous & filthy place”

Pelosi called Trump’s attack on Cummings “racist.”

“@RepCummings is a champion in the Congress and the country for civil rights and economic justice, a beloved leader in Baltimore, and deeply valued colleague,” Pelosi tweeted. “We all reject racist attacks against him and support his steadfast leadership.”
