Venezuela's Citgo Petroleum Corp. resumed deliveries of free heating oil to poor Americans on Thursday, making its first delivery since the program's rumored end. Together with Boston-based partner Citizen's Energy Corp., Citgo delivered more than 200 gallons of heating oil to the Dorothy Day Catholic Worker House, a transitional shelter in Washington, DC. "It's so cold, apartment rents are so high, and people are out of work," said volunteer and resident Kathy Boylan, 65, in a telephone interview from Washington about the 4-year-old program. "People need this help tremendously." Citgo announced Jan. 7 that the free fuel shipments would continue - two days after Citizen's Energy said they were suspended in the world economic crisis.
