First Thing: Biden to issue order on new restrictions at US-Mexico border

President’s move comes amid voter dissatisfaction over migration, while progressive and Latino lawmakers express alarm. Plus, world’s first personalized cancer vaccine halves the risk of death from melanoma

Good morning.

Joe Biden is expected to announce an executive order on Tuesday that would instruct authorities to temporarily seal the border with Mexico when illegal crossings exceed a daily threshold, in the harshest border action taken so far by his administration.

The order would end asylum requests to the US-Mexico border once 2,500 daily encounters are recorded between legal ports of entry.

The move follows mounting pressure from Republicans and some Democrats and comes amid rising public concern about the number of people reaching the US southern border. The Biden administration’s previous attempt to reach a bipartisan border security deal failed after Donald Trump opposed it to avoid handing Biden a victory on the former president’s key policy platform.

What’s been the reaction? Many progressive and Hispanic lawmakers were alarmed at the comprehensive order, and legal challenges are expected.

Melanoma jab trial results excite doctors

The world’s first personalized mRNA cancer vaccine for melanoma halves the risk of patients dying or the disease returning, trial results show.

For patients who received the jab after the removal of a stage 3 or 4 melanoma, the risk of dying or relapse after three years fell by 49%, data showed – a result doctors hailed as “extremely impressive”.

On average, advanced cancer patients face a 50% risk of cancer recurrence after surgery, according to oncologist Prof Georgina Long, who was a primary investigator on the study. While longer-term data needs to be analyzed, Long said patients in this group faced the highest risk of recurrence within two years of surgery.

How does it work? The jab, which is personalized for each patient, instructs their body to kill any remaining cancer cells and stop the disease from returning.

Benjamin Netanyahu to address joint session of US Congress for fourth time

The Israeli prime minister, Benjamin Netanyahu, will become the first foreign leader to address a joint session of the US Congress four times, following a formal invitation from congressional leaders of both parties.

Netanyahu was invited after Biden’s disclosure of the terms of a new Gaza peace proposal. While the plan had Israel’s backing, Netanyahu over the weekend downplayed the importance of Israeli concessions in the proposed truce, saying a lasting ceasefire that did not involve destroying Hamas would be a “nonstarter”. Analysts warn of the threat of a “forever war” as Hamas has been able to return to areas from which it was earlier defeated.

Netanyahu’s comments on the proposal follow earlier defiance toward the Biden administration, where he strongly opposed any steps towards a two-state solution, and proceeded with the Rafah offensive despite repeated appeals from the White House.

How has Hamas responded to the proposal? The White House said it awaited the group’s official response.

What’s the latest on US protests? San Francisco police on Monday arrested 70 pro-Palestinian demonstrators who occupied the lobby of a building that houses the Israeli consulate.
