A former Brazil health ministry official at the center of a vaccine-buying scandal was briefly detained amid a congressional hearing, the latest chapter in the televised drama that is eroding support for President Jair Bolsonaro. Roberto Dias left a senate committee room Wednesday with an escort of legislative police after being accused of lying during daylong testimony. His arrest, which was ordered after senators heard audio recordings in the case, lasted just a few hours: he was released later in the evening after posting bail of 1,100 reais ($208.)
