President Donald Trump intensified immigration arrests across the United States this week while Democrats faced a leadership revolt following their midterm victory that returned them to control of both chambers of Congress.

The enforcement push continued despite the Republican loss in last week's midterm elections. In Los Angeles, masked immigration officers in body armor blocked a hospital emergency room driveway in a heavily Latino neighborhood early Saturday. In central Alabama, twin 19-year-old brothers from Venezuela were arrested while driving back to college a day after the election. Advocates reported arrests from California to Michigan to Massachusetts.

Trump said his immigration crackdown may have been "too tough" in a CBS "60 Minutes" interview recorded Friday, suggesting it was time to sit down with Democrats. Hours later, he named Stephen Miller, the architect of his hardline immigration agenda, as his new chief of staff. Homeland Security Secretary Markwayne Mullin said his orders had not changed. "Deportations will continue," Mullin wrote in an online post the day after the election.

Specific incidents included a married couple from Orlando arrested at the Phoenix airport while traveling to a funeral, and Florida Highway Patrol officers detaining people in cars, supermarkets and gas stations. Immigrants under supervision were arrested when they showed up at ICE's Miami office for appointments. The Department of Homeland Security declined to explain the officers' presence at the Los Angeles hospital but said "ICE does not target hospitals, schools, or churches."

Democrats confronted internal divisions over their congressional leadership. Sen. Bernie Sanders of Vermont said Tuesday he would not support Sen. Chuck Schumer of New York for reelection as Democratic leader. "I like Chuck. Nobody works harder than Chuck Schumer. But in my view, the time is now for change," Sanders said.

Schumer said he was "confident I will be elected majority leader." Sen. Elissa Slotkin of Michigan demanded a plan for change while saying she was not "actively seeking the job." Sen. Chris Van Hollen of Maryland was listening to calls to run for Democratic leader while also considering a presidential campaign.

In the House, Rep. Hakeem Jeffries of New York dismissed challenges to his leadership. "You think I don't have the vote nailed down? I guess we'll find out next Wednesday," he told reporters Monday. He has support from progressive incumbents including Reps. Alexandria Ocasio-Cortez, Pramila Jayapal and Ro Khanna.

But incoming Democratic freshmen signaled they might defy party leaders. Rep.-elect Don Leonard of Ohio said it "aches" his heart to potentially oppose the first Black speaker, but "Rome is burning." Rep.-elect Randy Villegas of California said, "I think we need to see some prioritization of some legislation, particularly around health care, foreign policy and immigration."

The Democratic turmoil contrasts with the Republican leadership elections concluded Tuesday. Senate Republicans chose Sen. John Thune as majority leader by acclamation, while House Republicans elected Rep. Jim Jordan as minority leader, defeating Rep. Steve Scalise 106-73 in a secret ballot.
