Republican Senator Tom Coburn has been identified as the lawmaker responsible for holding up over $900 million in congressionally approved aid for Haiti. A supplemental request for Haiti reconstruction passed the Senate in May and then the House in July. But a measure to direct how the money is spent was held up after it was anonymously tabled for further review. The Associated Press reports that Coburn, a doctor, pulled the measure over concerns about a $5 million provision that he says would waste taxpayer dollars. The US still hasn’t delivered a cent of the $1.15 billion in new aid for Haiti it pledged earlier this year. At least six people were killed and over 8,000 tarps and other temporary shelters were destroyed when a storm hit the capital Port-au-Prince last week.
