Colorado has strengthened its gun regulations on the eve of the 22nd anniversary of the Columbine High School massacre.

For the record: The two measures were introduced in the state legislature before last month's fatal shooting at a grocery store that left 10 people dead. One bill is named for a 21-year-old woman who was fatally shot by a gunman with a stolen weapon.

Details: The Isabella Joy Thallas Act requires firearms owners to report the loss or theft of a weapon to law enforcement within five days of its disappearance.

  • The other law, designed to ensure the safe storage of firearms, is due to take effect on July 1.
  • "Every year, thousands of gun deaths nationwide and hundreds of gun deaths in Colorado occur because of improperly and unsafely stored firearms," per an emailed statement. "Additionally, people who live in homes with guns stored in an unsafe manner are more likely to commit suicide."
"This bill will reduce gun deaths by requiring that firearms be securely stored when not in use, and requiring licensed gun dealers to provide a storage device with the purchase of firearms."

What they're saying: Gov. Jared Polis (D) noted at a news conference on Monday, when he signed the bills that while the laws "can prevent future loss of life" and "be part of the healing for the Thallas family and so many others impacted by gun violence by a stolen gun."

  • State Sen. Steve Fenberg (D-Boulder) said Tuesday that more legislation to address the circumstances of the Boulder shooting is coming.
  • The legislation will likely look at “things that can be responsive to what happened in Boulder, and save as many lives as possible,” Fenberg, the state Senate’s majority leader, said. “We want to make sure that whatever we introduce can pass.”

Of note: "No Republicans in the General Assembly supported either bill, saying they infringe on gun owners’ rights and criminalize gun owners," the Denver Post reports.

Axios Denver's John Frank contributed to this report.

Inside Biden's Taiwan flubs

Twice this year, President Biden has blurted out commitments that the U.S. is prepared to defend Taiwan against a Chinese invasion — forcing the White House to walk back his statements and leading to confusion over a high-stakes national security policy.

Why it matters: U.S. defense officials have publicly aired their concerns that China will take Taiwan by force in the next four to six years, perhaps sooner. The president's position on this question may soon have real-world, life and death consequences.

A series of powerful "atmospheric river" storms are set dump historic amounts of rainfall across parts of drought-stricken California and the Pacific Northwest from this weekend, forecasters warn.

Why it matters: A strong atmospheric river, packing large amounts of moisture, is predicted to whiplash Northern California from drought to flood.

10,000 trees near giant sequoia groves to be removed after fires

"Upwards of" 10,000 trees near giant sequoia groves have been "weakened by drought, disease, age, and/or fire" and must be removed in the wake of California's wildfires, the Sequoia and Kings Canyon National Parks announced.

Why it matters: The damage to these trees, considered "national treasures," and work to remove them means a nearby key highway must remain closed to visitors as they have "the potential to strike people, cars, other structures, or create barriers to emergency response services," per a statement from the national parks.
