Rubio says Cuba leaders must go as US dangles US$100 million

US Senator Marco Rubio has stated that the leaders of Cuba must step down, as the US offers $100 million in aid. This move comes amidst ongoing tensions between the US and Cuba, with the US seeking to promote democratic change in the island nation. The situation highlights the complex and often contentious relationship between the two countries. The US offer of aid is seen as an attempt to encourage reform in Cuba, but it is unclear how the Cuban government will respond.
