Here’s what else you need to know to Start Your Week Smart.

The weekend that was

• Crews are searching for survivors and surveying the damage after tornadoes and strong thunderstorms tore through Tennessee, overturning cars, ripping apart buildings and leaving at least six people dead. As Clarksville looked for survivors and possibly additional victims, the mayor declared a state of emergency.
• In a stunning downfall for the leader of one of the world’s most prestigious universities, Liz Magill, the president of the University of Pennsylvania, stepped down from the helm of the Ivy League school following a torrent of criticism for her testimony about antisemitism on Capitol Hill. Board Chair Scott Bok also resigned.
• Teenager Ethan Crumbley was sentenced to life in prison without parole for gunning down four classmates and wounding six others and a teacher at Michigan’s Oxford High School in 2021. Judge Kwamé Rowe noted that the “defendant in his own words” told the court “this is nobody’s fault but his own.”
• An appeals court has largely upheld the gag order against Donald Trump in the federal election subversion case but said the gag order does not apply to comments made about special counsel Jack Smith.
• The US Food and Drug Administration approved two gene-based treatments for sickle cell disease, including the first therapy that uses the gene-editing technique CRISPR, opening a new era of treatments for genetic conditions.

The week ahead

Monday
Former President Donald Trump is expected to take the stand as the last witness for the defense in his New York civil fraud trial. This will be Trump’s second trip to the witness stand as he was called by the New York attorney general’s office. The high-stakes civil case strikes at the heart of Trump’s brand: his real estate empire. New York Attorney General Letitia James is suing Trump for $250 million and seeking to bar him from doing business in the state. Judge Arthur Engoron has already ruled that Trump and his co-defendants were liable for fraud. Trump’s defense team has argued that there was no intent to defraud banks or insurers, in part because the Trump family relied on accountants and that any differences in values on the properties were not meaningful.

Elsewhere in Trump’s orbit, a jury trial is set to begin to determine how much Rudy Giuliani will have to pay two election workers he was found to be liable for defaming. Giuliani was sued as the head of Trump’s legal team and a proponent of a disinformation effort that slandered Georgia election workers Ruby Freeman and Shaye Moss, causing them significant emotional distress. The judge has already found Giuliani liable for defamation, and the trial is to determine the monetary damages he must pay. Moss and Freeman are seeking tens of millions of dollars in damages from Giuliani. The trial is set to last four days.

Tuesday
CNN will host the first of two town halls in Iowa before the state’s Republican caucuses in mid-January. Florida Gov. Ron DeSantis will take the stage at 9 p.m. ET from Grand View University in Des Moines. CNN’s Jake Tapper will moderate.

Wednesday
CNN’s second town hall will feature entrepreneur Vivek Ramaswamy. The event — also at 9 p.m. ET — will be moderated by CNN’s Abby Phillip from Grand View University.

The Federal Reserve wraps up its last interest rate meeting of the year. No change is expected, and investors are already looking toward the possibility of rate cuts next year.
