House Minority Leader Kevin McCarthy will travel to Texas on Monday with roughly a dozen Republican members to assess the growing crisis at the southern border, his office confirmed to Axios.

Why it matters: The visit comes as President Biden is under increased pressure to address the overwhelming flow of unaccompanied migrant children at the U.S.-Mexico border. Recent data shows an average of 321 kids being referred to migrant shelters each day, as Axios first reported.

What we're hearing: McCarthy sent a letter to the president last Friday requesting a meeting with him to discuss the situation. A source familiar with the letter told Axios that McCarthy has yet to receive a response.

  • "I feel compelled to express great concern with the manner in which your administration is approaching this crisis, but with hope that we can work together to solve it," McCarthy had written in the letter.
  • Among those who will join him on the trip are Reps. John Katko of New York and Tony Gonzales of Texas.

The backdrop: Homeland Security Secretary Alejandro Mayorkas led a visit to the border for Biden officials — including domestic policy adviser Susan Rice — on Saturday.

  • The group went to a Border Patrol facility and a refugee resettlement facility, the White House said in a statement on Sunday, according to Reuters.
  • Republicans from the Texas congressional delegation also plan to visit McAllen, Laredo and Eagle Pass, Texas, between March 29 and 31, a source familiar with the plans tells Axios.

Perfect storm brewing for extreme politicians

Data: Axios research; Table: Jacque Schrag/Axios

Redistricting and a flood of departing incumbents are paving the way for more extreme candidates in this year's midterm elections.

Driving the news: At least 19 House districts in 12 states are primed to attract such candidates — hard partisans running in strongly partisan districts — according to an Axios analysis of districts as measured by the Cook Political Report's Partisan Voter Index (PVI).

3D printing's next act: big metal objects

A new metal 3D printing technology could revolutionize the way large industrial products like planes and cars are made, reducing the cost and carbon footprint of mass manufacturing.

Why it matters: 3D printing — also called additive manufacturing — has been used since the 1980s to make small plastic parts and prototypes. Metal printing is newer, and the challenge has been figuring out how to make things like large car parts faster and cheaper than traditional methods.

Mayors see cryptocurrency as a way to address income inequality

At the U.S. Conference of Mayors' meeting in D.C. this week, there's buzz around the idea of giving cryptocurrency accounts to low-income people.

Why it matters: Cities have been experimenting with newfangled ways to address income inequality — like guaranteed income programs — and the latest wave of trials could involve paying benefits or dividends in bitcoin, stablecoin or other digital currencies.
