Lt. Col. Alexander Vindman, who served as a key witness in President Trump's impeachment trial, announced Wednesday that he has moved to retire from the military after 21 years of service amid fears that he will "forever be limited" due to political backlash over his testimony.

The big picture: The president fired Vindman in February as the leading Ukraine expert on the National Security Council for being "insubordinate," but top military leaders including Secretary of Defense Mark Esper claim Vindman had not been politically targeted.

  • In his testimony, Vindman called Trump's push for Ukraine to investigate former Vice President Joe Biden "inappropriate" and said he reported his concerns on the matter due to a "sense of duty."
  • Sen. Tammy Duckworth (D-Ill.) vowed last week to block the promotions of 1,123 senior military officers until Esper confirmed that Vindman's promotion would go through.

What they're saying: "Through a campaign of bullying, intimidation and retaliation, the president of the United States attempted to force LTC Vindman to choose: Between adhering to the law or pleasing a president. Between honoring his oath or protecting his career. Between protecting his promotion or the promotion of his fellow soldiers, " Vindman's lawyer, Amb. David Pressman, said in a statement.

  • "These are choices that no one in the United States should confront, especially one who has dedicated his life to serving it," Pressman added.

Flashback: In concluding his opening statement at the impeachment hearing, Vindman emotionally addressed his immigrant father: "You made the right decision 40 years ago to leave the Soviet Union and come here to the United States of America in search of a better life for our family. Do not worry. I will be fine for telling the truth."

Air quality alerts issued as California fires threaten more sequoias

Two wildfires were threatening California's sequoia trees over overnight — hours after authorities issued fresh evacuation orders and warnings, along with air quality alerts.

The big picture: Air quality alerts were issued Wednesday for the Bay Area and the San Joaquin Valley as smoke from the Windy and KNP Complex fires resulted in hazy, "ash-filled" skies from Fresno to Tulare, the Los Angeles Times notes.

Asymptomatic Florida students exposed to COVID no longer have to quarantine

Florida Gov. Ron DeSantis (R) announced Wednesday an emergency order allowing parents to decide whether their children should quarantine or stay in school if they're exposed to COVID-19, provided they're asymptomatic.

Why it matters: People infected with COVID-19 can spread the coronavirus starting from two days before they display symptoms, according to the CDC. Quarantine helps prevent the virus' spread.

Federal judge: Florida ban on sanctuary cities racially motivated

A federal judge on Tuesday struck down parts of a Florida law aimed at banning local governments from establishing sanctuary city policies, arguing in part that the law is racially motivated and that it has the support of hate groups.

Why it matters: In a 110-page ruling issued Tuesday, U.S. District Judge Beth Bloom said the law — signed and championed by Gov. Ron DeSantis (R) — violates the Constitution's Equal Protection Clause because it was adopted with discriminatory motives.
