Sen. Mitt Romney (R-Utah) is standing as a maverick in his party, coming out as one of few Republicans to openly question President Trump's disputed conversation with Ukrainian President Volodymyr Zelensky.

Driving the news: Romney tweeted last Sunday: "If the President asked or pressured Ukraine’s president to investigate his political rival, either directly or through his personal attorney, it would be troubling in the extreme." He also told NBC on Monday that Trump should make the whistleblower complaint available to Congress because it would be "very helpful to get [to] the bottom of the facts."

  • A summary of the call released by the Trump administration on Wednesday shows that the president asked Zelensky to investigate former Vice President Joe Biden and his son, Hunter.
"There's a lot of talk about Biden's son, that Biden stopped the prosecution and a lot of people want to find out about that so whatever you can do with the Attorney General would be great. Biden went around bragging that he stopped the prosecution so if you can look into it ... It sounds horrible to me."
— President Trump

Shortly after the transcript's release, Romney spoke at The Atlantic Festival about why he's pushing back against the president, stating:

"I think it’s very natural for people to look at circumstances and see them in the light that’s most amenable to their maintaining power, and doing things to preserve that power."

Context: Trump and Romney have a rocky history. In 2016, Romney called Trump "a fraud" and attempted to rally voters behind one of Trump's primary competitors. But shortly after Trump's election, the 2 seemingly rekindled their relationship, as Trump met with Romney while mulling over Cabinet nominees and later endorsed him in Romney's 2018 Senate bid.

Between the lines:

  • Wednesday's transcript release and subsequent fallout comes after the announcement that the House will launch a formal impeachment inquiry against the president.
  • Articles of impeachment would ultimately be decided by a trial in the Republican-controlled Senate. For now, it seems unlikely the Senate will enter a judgment to convict.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

U.S. vs. Google — the siege begins

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
