US Secretary of State Marco Rubio defended the US operation to arrest Venezuela's president Nicolas Maduro, saying congressional authorisation was not required. "It wasn't necessary because this is not an invasion. We didn't occupy a country. This was an arrest operation," Rubio said on ABC's 'This Week with George Stephanopoulos' on Jan 4. https://cna.asia/3Ykgg2D #unitedstates #venezuela #usnews | CNA
