Brazil's President Luiz Inacio Lula da Silva and his main challenger Flavio Bolsonaro wrapped up their campaigns on Saturday in the powerhouse state of Sao Paulo, where a fifth of the nation's vote is based, seeking to rally supporters and convince the undecided on the eve of Sunday's nail-biter election.

The head of Tennessee's prison system has resigned in the first major shake-up since the stunning failed execution of convicted murderer Christa Pike, who is in critical condition after surviving two lethal injections. Tennessee Governor Bill Lee, who previously denied Pike clemency, has halted further executions through the rest of the year while a review is conducted.

The mudslinging between Brazil’s incumbent President Luiz Inacio Lula da Silva and his election rival, Flavio Bolsonaro, has heated up ahead of what is expected to be an extremely close vote this weekend. From stating loose rumours as facts, to taking comments completely out of their context, they are both doing everything they can to win a few more votes.

Christa Pike, who has been on death row in Tennessee for more than 30 years for torturing and murdering a classmate, was on Wednesday set to be executed, but the lethal injections meant to kill her failed. Pike was then transported to a medical facility, where her attorney says she remains in a "critical condition".

US Defence Secretary Pete Hegseth said Wednesday that his department had cut 20 percent of US admirals, generals and officers who did not fit his vision. "Simple translation of that: no fatties, no trannies, no beardos, no weirdos, no wimps, no radicals. Just warriors – just tough, ready, committed troops," he said.

El Salvador will hold presidential elections on February 28, 2027, the electoral tribunal said Wednesday, opening the way for President Nayib Bukele to seek a third term after constitutional changes removed presidential term limits. Bukele has drawn praise for sharply reducing gang violence but faced criticism over rights abuses during his crackdown.

The Federal Reserve's watchdog on Wednesday found no grounds for a criminal referral over a roughly $1 billion cost overrun on renovations to the central bank's Washington buildings, while faulting project oversight. The findings prompted President Donald Trump to renew his call for former Fed chief Jerome Powell to resign.

A federal judge on Wednesday approved a settlement clearing Paramount’s takeover of Warner Bros. Discovery after 12 US states challenged the deal on antitrust grounds. The agreement includes safeguards for CNN’s editorial independence and requires the merged studio to release at least 30 films a year for its first two years.

The US Supreme Court on Wednesday cleared the way for Tennessee to execute Christa Pike, 50, the state's first woman put to death in 200 years. The ruling came hours after a federal appeals court temporarily halted the lethal injection to consider claims that Pike's childhood sexual abuse was not adequately weighed at sentencing.
