Twitter said Tuesday its user base jumped to 192 million in the quarter marked by the heated US presidential election and a battle against misinformation. Ranks of daily active Twitter users rose 27 percent from a year earlier during the fourth quarter, which produced a $222 million profit for the messaging platform favored by former president Donald Trump before his de-platforming in January. Chief executive Jack Dorsey said the San Francisco platform remained focused on "promoting healthier conversations for those who use our service." gc/rl
