A bar chart spanning three slides showing the total value of foreign gifts given to U.S. presidents between 2001 and 2023. Barack Obama received the largest total value in gifts, at $2.0m, followed by George W. Bush, $1.1m. The possible gift of a $400m Qatari plane is shown as an incredibly long bar that wraps back and forth across the page. If it were accepted, it would dwarf all the other gifts by far.A continuation of the previous imageA continuation of the previous image

ABC News has now fully taken down the old 538 website, including all interactive projects since 2014. Aside from erasing history this prevents access to publicly released data, including raw polls, averages, model estimates & story dta. Totally unacceptable for a company (allegedly) doing journalism

As reported, the entire staff of 538 was laid off this morning. This is a severe blow to political data journalism, and I feel for my colleagues. Readers note: As we were instructed not to publish any new content, all planned updates to polls data and averages are canceled indefinitely. Huge loss :(
