Here's a roundup of news trending across the nation and world today.

What to know now:

1. Thank you tour: On Thursday, president-elect Donald Trump and vice president-elect Mike Pence will begin a swing of the states that gave them the win in Electoral College voting. Their first stop on the "thank you tour" will be in Cincinnati, but before heading to Ohio, Trump and Pence will be in Indiana where they will celebrate the decision by Carrier to keep nearly 1,000 jobs in the United States instead of moving them to Mexico. Trump had promised if he were to be elected that he would work to keep Carrier from moving the jobs out of the country.

2. Officer killed: A Tacoma, Wash., police officer was shot and killed late Wednesday after responding to a domestic violence call, officials said. The officer, who has not been identified, was shot by a man who barricaded himself in his home. As of early Thursday, the man had not surrendered.

3. Pelosi re-elected: Nancy Pelosi (D-Calif.) was re-elected on Wednesday as House Minority Leader, fending off a challenge from Rep. Tim Ryan (D-Ohio). The vote, held behind closed doors, was said to be 134 for Pelosi and 63 for Ryan. Ryan had called for a change in his party, saying Democrats needed to re-engage with disenfranchised black voters and to change their economic message.

4. Recount set to begin: The recount of Wisconsin's presidential vote is expected to begin Thursday. Green Party candidate Jill Stein put up the $3.5 million on Tuesday to pay for the recount in all the state's 72 counties. Hillary Clinton's campaign is supporting Stein in the recount effort. Stein has also asked for a recount in Pennsylvania and is expected to request one in Michigan.

5. Drug could relieve cancer anxiety: A pair of studies of a drug called psilocybin suggests that it is effective in relieving anxiety and depression in cancer patients. The drug, a hallucinogenic, has been shown to lift the mood of patients in studies at two medical centers in the United States. Psilocybin, referred to as "magic mushroom," is known to produce visions and "mystical experiences."

The pop icon Prince left an estate worth around $200 million when he died of a drug overdose in April, according to a new court filing. The assets come from his music catalog, his Paisley Park home and studio and unreleased music. Prince died without a will, so the estate will be divided between his sister and five half-siblings.
