The son of the former president, Mahinda Rajapaksa said he was blocked from entering the United States this week after spending time in Moscow as an election observer.
"I won't make my Houston Flight as #US Officials instruct them to not let me board. Sure it has nothing to do with my name, being part of #lka opposition or my travel from #Russia," he tweeted yesterday.
Mr Namal Rajapaksa has been charged with money laundering in Sri Lanka, along side other family members.
