Consumer price index report and Juan Soto's free agency: Morning Rundown

Donald Trump will meet with Joe Biden at the White House. The latest consumer price index is expected to show a slight increase for October. And a test that uses DNA to help diagnose medical mysteries was deemed a "breakthrough device."

Here's what to know today.

Trump returns to White House for symbolic meeting President-elect Donald Trump will meet with President Joe Biden today in a symbolic White House ceremony meant to signal the peaceful transfer of power. It's a meeting Trump denied to Biden in 2020 when he refused to concede the election results and worked to delay Biden's taking office. It's also Trump's first time back in the White House since he was voted out of office.

There are still a few unknowns for the day, including whether Vice President-elect JD Vance will be part of the trip. Vance has yet to hear from Harris about a potential visit, a source familiar with discussions said. In addition to Trump, the White House extended an invitation to Melania Trump, but a source familiar with the planning said she is not expected to accompany her husband.

Before going to the White House, Trump is expected to address House Republicans and could also meet with Senate Republicans. Both chambers are scheduled to elect their leadership teams in closed-door meetings.

In the Senate, Republicans will select a leader to replace Mitch McConnell as he steps down from his post. The three-way race is between Sens. John Thune, the current whip; John Cornyn, a former whip; and Rick Scott, an underdog candidate. Thune and Cornyn are from the institutionalist wing of the GOP, and both have long-standing relationships with the conference. Scott, first elected in 2018, is a more divisive figure who has picked up endorsements from some Trump allies. All three candidates have vowed to carry out Trump's agenda.

In the House, Republicans are expected to nominate Speaker Mike Johnson, though he could face a symbolic challenge as the House Freedom Caucus, under new chairman Rep. Andy Harris, considers whether to nominate someone to run against him. Read more about the House leadership vote.

Progress on inflation has most likely stalled for now Consumer prices likely rose slightly in the month leading up to Trump's election win, according to analysts' predictions of the Bureau of Labor Statistics consumer price index for October. The expected figure is a 2.6% rise in prices, up from a 2.4% uptick in September. "Core" inflation, a measure that excludes food and energy prices, is forecast to remain at 3.3%.

The latest figures provide a snapshot of the climate in which voters were casting their ballots. Steeper expenses for child care and home insurance left many people fed up and looking for change. But it's not yet clear whether Trump will be able to replicate the steady growth and low inflation from the period before Covid hit, and some economists fear Trump's proposals, like his plans for much higher tariffs and deeper tax cuts, could set off another round of price growth

Cutting-edge test yields diagnoses for some medical mysteries A diagnostic test that uses genetic sequencing to detect a variety of pathogens can help doctors solve medical mysteries, a pair of studies has revealed. The test, developed at the University of California, San Francisco, extracts the DNA and RNA from a sample of blood, tissue or body fluid, and then sequences the genetic material and compares the sequences to a vast database of viruses, bacteria, fungi and parasites to see what matches up. In research released this week, the test was shown to be effective at identifying the cause of neurological infections such as meningitis and has helped doctors pinpoint the cause of a meningitis outbreak in Mexico.

The FDA granted the test a "breakthrough device" designation, meaning labs can use the test even though the agency hasn't approved it yet. However, several limitations mean widespread use, at least any time soon, is unlikely. Here's why.
