State and local governments across the country are trying to alleviate housing shortages by allowing denser development in areas dominated by single-family homes, Axios' Caitlin Owens reports.

• Why it matters: That has sparked a backlash from many current homeowners — who like their neighborhoods the way they are.

What's happening: Low-density neighborhoods are often zoned so that only single-family homes can be built there. Advocates are pushing local governments to loosen those rules and allow multiple types of housing.

• "There certainly is a widespread fear of housing becoming increasingly unaffordable to a large share of the population, and the remedy that is being discussed nationwide [is] changing zoning rules," said Yonah Freemark, a researcher at the Urban Institute.
• Changing zoning laws is an especially attractive option because it can increase supply at no cost to the government, Freemark said.

Case in point: Arlington County, Va., has been mired in a fierce debate over proposals to allow more "missing middle" housing — buildings like duplexes that aren't single-family homes or large apartment complexes.

• The county board decided to allow more of that construction, despite loud opposition from some homeowners.
• Nearby Alexandria launched its own initiative to examine and change its zoning code.

The other side: Some opponents fear the changes could harm existing homeowners through deflated property values and increased stress on infrastructure.

• They've successfully blocked some rezoning efforts. Arizona's housing push died in the state Senate, although reform supporters are still pushing alternative proposals, Axios Phoenix reports.

👀 What we're watching: New York Gov. Kathy Hochul's housing plan — which includes new housing targets and rezoning measures — is being applauded by supporters as an ambitious approach to the state's housing problems, but comes with major political risk.

• Some see it "as the policy equivalent of an extinction-level event and a bizarrely self-defeating move from a governor who risks permanently alienating the suburban voters she’ll need to win reelection in three years," Bloomberg reported.

Manhattan District Attorney Alvin Bragg has gone public with details of death threats and what he calls "violent and racist vitriol" from Trump allies in the week since the former president was indicted.

• The raw revelations are contained in an unusual 50-page lawsuit Bragg filed yesterday aimed at House Judiciary Chairman Jim Jordan (R-Ohio).
• The suit says the D.A.'s office has received more than 1,000 calls and emails from Trump supporters — "many of which are threatening and racially charged."

Why it matters: The lawsuit is part of the prosecutor's ferocious resistance to GOP efforts to call him to testify, Axios' Stef Kight and Sophia Cai report.

Between the lines: It sometimes took House Democrats years to enforce their subpoenas in various Trump investigations. Now this lawsuit could slow down GOP efforts to investigate Bragg.

• The suit attempts to block Republicans from demanding certain documents and subpoenaing witness testimony about Bragg's work.
• The judge in the subpoena case, U.S. District Judge Mary Kay Vyskocil, denied Bragg lawyers' request for a temporary restraining order.

Alyssa DaCunha, co-chair of WilmerHale's congressional investigations practice, predicted the Bragg suit unlikely to prevail, but told Axios it would take time and tie up House Judiciary resources.

• Former Nixon White House counsel John Dean tweeted: "Brilliant move by DA Bragg to block frivolous subpoenas from House Judiciary Committee by seeking a declaratory judgment in the US District Court" in the Southern District of New York.

Jordan told Fox News "Special Report" anchor Bret Baier: "They are obstructing our constitutional duty to do oversight."

• Jordan added his committee is planning legislation that would require future, similar cases to be moved to a federal court.

The White House has adopted a nuanced posture with its climate rules for vehicles: The proposed regulations ride the currents of existing market trends while forcing the industry to go further, Ben Geman writes in Axios Generate.

• Why it matters: The EPA draft is aimed at accelerating growth of electric vehicles to fight climate change.

🧠 How it works: The rules set CO2 limits for cars, SUVs and pickups for model years 2027-2032, and heavy-duty vehicles for the same period.

• They don't mandate specific tech, but instead set declining limits on fleet-wide grams of CO2 per mile.
• However, they're strict enough to effectively require far more EVs, in addition to better efficiency of gas-powered models.

🧮 By the numbers: The EPA estimates its main proposal would mean EVs rising to 60% of light-duty sales — sedans, SUVs, pickups and vans — by 203o, and 67% in 2032. That's up from roughly 10% today.

• Electric models would be 50% of sales of new vocational vehicles (such as buses and garbage trucks) in 2032.
