President Trump warned congressional Republicans during a visit to the Capitol today to not to "f**k around" with Medicaid, Axios' Andrew Solender and Victoria Knight write.

• It was a stark pushback to conservative lawmakers demanding steeper cuts to the program in Trump's "one big, beautiful bill."

Why it matters: Trump is already floating political retribution for Republican holdouts who don't get in line.

💬 The president also tore into Rep. Thomas Massie (R-Ky.), who has been a firm "no" on the bill throughout the process, blasting him publicly and privately as a "grandstander" and saying he should be "voted out of office."

• Trump warned the GOP's blue state holdouts not to push too hard on the SALT deduction cap.

👀 The intrigue: House Speaker Mike Johnson cautioned the Senate at a closed-door lunch today not to make big changes to the bill, Axios' Stef Kight scooped.

• If Johnson can get his conference in line, his problem will soon move to Senate Majority Leader John Thune (R-S.D.) — with an important July deadline looming on the debt ceiling.

Sources tell Axios that Johnson projected a lot of confidence in the meeting.

Elon Musk said he plans to spend "a lot less" on political donations moving forward during a remote interview at Bloomberg's Qatar Economic Forum today.

• Musk spent more than $250 million in a push to return Trump to the White House — and pulling back could come as a disappointment for Republicans in 2026.

The Tesla CEO also vowed to exact vengeance on people who violently targeted Tesla over his political support for Trump.

• "We are coming for those who organized the violence & death threats against Tesla," Musk said on X. "Remember this statement."

Ever notice the plethora of star ratings on sites like Amazon or Tripadvisor?

• Visual star customer ratings are perceived as being higher than those presented numerically, Axios' Felix Salmon writes.

Why it matters: Consumers evaluate ratings differently depending on the format in which the ratings are presented, per a new paper published in the Journal of Marketing Research.

The big picture: When we see pictures of stars, we count how many lit-up stars there are, including any partially lit stars. When we see a number, we focus on the initial digit.

• Let's say someone uses a moon-based rating system and gives an object 2.5 moons out of 5.
• When asked, some 70% of respondents will say that's "around two moons" since most people round down rather than up.
• On the other hand, if the same object gets a rating of 🌕🌕🌗🌑🌑, 80% of respondents will say that's "around three moons" since most people round up rather than down.
