Samsung just couldn't wait until Tuesday's Unpacked event to show off its new foldable smartphone. The company used a commercial during the Oscars to tease the new phone, which has already been widely leaked.

The big picture: Foldables, led by the original Galaxy Fold and Motorola's Razr, are the current novelty of the smartphone market.

  • While the new foldable, expected to be called the Galaxy Z Flip, is likely to be the toast of the Tuesday event, the mainstay is the next generation of the Galaxy S family, which has also widely leaked, and is expected to be dubbed the Galaxy S20.
  • Also over the weekend, T.M. Roh, Samsung's new head of mobile communications, published a blog post touting, among other things, the company's work with Google and Microsoft.

Former Vice President Walter Mondale wrote a farewell letter to his staff, sent upon his death on Monday, thanking them for years working together.

Dear Team,

Well my time has come. I am eager to rejoin Joan and Eleanor. Before I Go I wanted to let you know how much you mean to me. Never has a public servant had a better group of people working at their side!

Together we have accomplished so much and I know you will keep up the good fight.

Joe in the White House certainly helps.

I always knew it would be okay if I arrived some place and was greeted by one of you!

My best to all of you!

Walter Mondale, who transformed the role of U.S. vice president while serving under Jimmy Carter and was the Democratic nominee for president in 1984, died Monday at 93, according to a family spokesperson.

The big picture: President Biden, who was mentored by Mondale through the years, said in 2015 that the former vice president gave him a "roadmap" to successfully take on the job.

The United States ambassador to Russia is refusing to leave the country after the Kremlin "advised" him to return home following new Biden administration sanctions, two sources briefed on the situation tell Axios.

Why it matters: John Sullivan, a respected diplomat who President Biden has, so far, retained from the Trump era, is at the center of one of the most important early tests of Biden's resolve.
