President Donald Trump on Sunday stepped up his criticism of Barack Obama's response to concerns Russia was trying to disrupt the 2016 election, and some Democratic lawmakers agreed, with one calling the former leader's handling of the threat a "serious mistake." In a flurry of weekend tweets and a prerecorded television appearance, Trump said his predecessor failed to act after the CIA informed him in August that Russian President Vladimir Putin had personally ordered an operation to help Trump defeat Hillary Clinton in the November election. "Since the Obama Administration was told way before the 2016 Election that the Russians were meddling, why no action?" he asked in one tweet.

Germany eased into the Confederations Cup semi-finals with a 3-1 win over Cameroon on Sunday as the VAR system was again thrust into the spotlight when the on-field official needed two reviews of an incident to reach the right verdict. Colombian referee Wilmar Roldan consulted the Video Assistant Referee (VAR) after a reckless high challenge by Ernest Mabouka on Germany's Emre Can saw Sebastien Siani wrongly receive a yellow card in a case of mistaken identity. It was only after Cameroon's players insisted he review the incident again that he realised his error, rescinded Siani's sending off and instead flashed the red card to the correct culprit Mabouka.
