U.S. Senator Bernie Sanders formally requested the Iowa Democratic Party recount some of the state’s results from last week’s caucus, citing 28 precincts where the campaign believes he was shorted delegates.

ā€œWhile a recanvass is just the first step in the process and we don’t expect it to change the current calculations, it is a necessary part of making sure Iowans can trust the final results of the caucus,ā€ Bernie 2020 Senior Advisor Jeff Weaver said.

Sanders narrowly lost to rival Pete Buttigieg in the Feb. 3 nominating contest, which took days to settle after a technical meltdown led to delays in determining the winner.
