But it creates thorny political challenges for border-region Democrats who face the likely prospect of an increase in migrants who have for two years been denied the chance to seek asylum in the United States.

In unusually harsh critiques of a president from their own party, some of the congressional Democrats with the toughest reelection prospects are warning that the administration is woefully unprepared to handle the situation.

“This is a crisis, and in my estimation, because of a lack of planning from the administration, it’s about to get worse,” said Sen. Mark Kelly of Arizona.

Kelly and fellow Arizona Democratic Sen. Kyrsten Sinema met Wednesday with Homeland Security Secretary Alejandro Mayorkas to press their case for the administration to better plan and coordinate a response. Last week, they wrote to President Joe Biden urging him to delay ending the pandemic rules until his administration is “completely ready to execute and coordinate a comprehensive plan that ensures a secure, orderly, and humane process at the border.”

Sinema and Texas Republican Sen. John Cornyn sent a similar letter to Mayorkas on Thursday.

Schumer Leads Effort to End Trump-Era Law

Migrants have been expelled from the U.S. more than 1.7 million times under public health powers invoked in March 2020 that are designed to prevent the spread of COVID-19. The Biden administration announced plans Friday to end Title 42 authority — named for a 1944 public health law — by May 23. Near the height of the omicron variant in late January, the U.S. Centers for Disease Control and Prevention had extended the order to this week.

The announcement comes after mounting pressure from many prominent Democrats, including Senate Majority Leader Chuck Schumer, to end a Trump-era program they cast as an excuse to wriggle out of obligations under U.S. law and international treaty to protect anyone fleeing persecution.

Kelly, Sinema, and other skeptical Democrats say the emergency powers must go away eventually, but they say the federal government has failed to develop and share plans to minimize the impact on communities near the border and the local religious and nonprofit groups that help migrants there.

“I’ve worked really hard to make it very clear to them that this situation is unacceptable, and they seem to get the message,” Kelly added. “It’s more challenging to get them to turn this into an actionable plan.”

Kelly in Battle to Keep His Senate Seat

Kelly, elected from once-solidly conservative Arizona, is among the most vulnerable Democrats in the Senate. He’s aggressively targeted by Republicans in what is already a tough year for Democrats who are fighting to hold onto their razor-thin majority in the Senate.

Kelly declined to discuss the impact of the decision on his tough reelection campaign, saying he’s focused on his job as senator.

“They know the realities of Arizona and its history, especially as a border state,” Mike Noble, a Phoenix-based pollster who used to consult for Republican campaigns but now focuses on nonpartisan polling, said of Arizona’s senators. “If they want to maintain their seats, they have to be tough on immigration, and if not, they could find themselves out of a job.”

Republicans see rising numbers of migrants as a winning issue with swing voters, particularly in border states like Arizona. An AP-NORC poll conducted in January found just 39% of Americans approve of how Biden is handling immigration. Eighty-seven percent of Republicans said they disapprove, but so did 34% of Democrats.

“The entire country sees the failure of the Biden administration and the laughing matter that this is to Kamala Harris, the self-appointed czar,” said Arizona Gov. Doug Ducey, the co-chair of the Republican Governors Association, which raises money to elect GOP governors. “They’re gonna pay a hell of a price at the ballot box in November. In every state.”

Manchin Wants Asylum Limits Kept in Place

Democratic Sen. Joe Manchin of West Virginia also has urged a delay in lifting Title 42, saying this stage in the pandemic is “not the time to throw caution to the wind.”

In Texas, Democratic Reps. Henry Cuellar and Vicente Gonzalez, both of whom represent border districts, joined Republicans in the Texas congressional delegation this week in expressing concern about ending Title 42.

“Small border communities lack the appropriate housing, transportation, and healthcare infrastructure to manage the ongoing release of migrant populations into their jurisdictions,” the lawmakers wrote.

Encapsulating internal divisions among Democrats, Cuellar’s progressive primary opponent, Jessica Cisneros, immediately seized on the issue, saying on Twitter that Cuellar’s support for keeping Title 42 amounts to “cruel and inhuman treatment of people whose stories and families resemble our own.”

Immigration Advocates Say Border Should Re-Open

Advocates for immigrants and refugees in Arizona say it’s long past time for the Biden administration to stop using public health rules to prevent people from claiming asylum.

Arizona’s senators seem to be looking at the border issue through a national political lens, said Joanna Williams, executive director of the Kino Border Initiative, which works in the twin border towns of Nogales, Arizona, and Nogales, Mexico.

“They are underestimating Arizonans,” Williams said. “We really have a community of hospitality that can arise to the occasion and help people. The senators need to listen to what people here are saying. This isn’t Texas.”

Alex Miller, director of asylum seekers and families for the International Rescue Committee in Arizona, said with coronavirus positivity rates among new arrivals now at less than 1% “the justification for closing the border is gone.”

“There is just no excuse for denying people fleeing from terrible abuse from getting asylum,” she said. “We have a moral responsibility to help these people.”
