Obama could axe meeting after Duterte threatens to "swear" at him. Vientiane/Hangzhou, China (dpa) - US President Barack Obama suggested he may cancel a scheduled bilateral meeting with Philippine President Rodrigo Duterte on Tuesday after Duterte said he would swear at the US president if he raised concerns about extrajudicial killings. “Son of a bitch, I will swear at you at that forum,” Duterte said, when asked how he would respond to questions about the spate of killings of suspected drug users and addicts under his administration.
