The ACLU is running an emotional two-page ad in the New York Times this Mother’s Day, urging the Biden administration to go beyond reuniting migrant children and parents separated by President Trump and guarantee them protections to stay in the U.S.

Details: The ad, previewed by Axios, depicts, in red ink, desperate, hand-scrawled fears of separated children against the backdrop of a growth chart.

Joint efforts to stem the increased number of migrants heading to the U.S. will likely be at the top of discussions when Vice President Kamala Harris and Mexico President Andrés Manuel López Obrador hold their virtual meeting on Friday.

The big picture: The U.S. government has consistently asked its southern neighbor to prevent immigrants from reaching the border, mostly through threats like former President Trump’s talk of tariffs.

The number of deportations under U.S. Immigration and Customs Enforcement (ICE) last month dropped to a record low, the Washington Post reports.

Why it matters: His promised 100-day moratorium on deportations was blocked by a federal judge, but the numbers from the Post show Biden's reversal of several ICE directives is having an impact.

President Biden will raise the cap on refugees to 62,500 this fiscal year, he announced on Monday.

Why it matters: The move comes after a wave of outrage over his initial decision to keep the Trump-era ceiling of 15,000 admissions in place.

Four families separated under the Trump administration's zero-tolerance policy will be reunited this week, Homeland Security Secretary Alejandro Mayorkas said on a call Sunday night.

Why it matters: Reuniting migrant families is one of Biden's biggest immigration-related promises and progress has been slow.

The Department of Homeland Security announced Friday it will begin repairing a broken flood barrier in Texas and a strip of eroding soil in California — issues that resulted from border wall construction in the respective areas.

The big picture: DHS said in a news release that the repairs were prompted by a "review the extensive problems created by the prior administration’s border wall construction" and are meant to "protect border communities from physical dangers..."

In a 6-3 decision, the Supreme Court ruled in favor of an undocumented Guatemalan immigrant who challenged his deportation.

The state of play: The majority opinion brought together an unusual coalition of conservative and liberal justices: Neil Gorsuch, who authored the opinion, and Clarence Thomas, Stephen Breyer, Sonia Sotomayor, Elena Kagan and Amy Coney Barrett.

• Gorsuch wrote that the Justice Department violated federal law by not providing Agusto Niz-Chavez with a single comprehensive "notice to appear," ABCNews reports.

The Justice Department has repealed a Trump-era order that cut off hundreds of millions of dollars in federal funding to cities that did not cooperate with Immigration and Customs Enforcement.

Why it matters: The 2017 order from President Trump was part of his larger crackdown on immigration. It faced a string of lawsuits from cities and states, per CNN, that argued such cooperation would deter immigrants from reporting crimes.

During his first 100 days, President Biden's successes at times have been overshadowed by news of the record number of migrant minors crossing the U.S.-Mexico border — overwhelming government resources.

By the numbers: There's still a record number of migrant children being held in shelters overseen by the Department of Health and Human Services, and the administration has had to open 13 emergency shelters since late February, sometimes through big contracts with nonprofit groups.

A poll and series of focus groups has honed a one-two punch for a doable immigration deal: Give Democratic lawmakers a real path to citizenship for Dreamers, and give Republicans tight border security that's more realistic than a wall.

Why it matters: The formula — by Frank Luntz, who rose to fame as a Republican pollster but in recent years has taken a more bipartisan approach to policy — would make real progress on one of the nation's biggest tragedies that Capitol Hill has failed to confront.
