FLINT, MI -- Democratic presidential candidate Bernie Sanders is questioning the cost of repairing Flint's infrastructure in comparison to the dollars used for the war in Iraq.

In a Sunday, April 3 Facebook post ahead of the Tuesday, April 5 Wisconsin primary against challenger Hillary Clinton during which 86 delegates are up for grabs, Sanders posed the question of the cost of the war and repairs for Flint.

"How did we have so much money to go to war in Iraq but somehow we don't have enough to rebuild the pipes in Flint?" reads the post, completed with the hashtag #FlintWaterCrisis.

Sanders has visited the city of Flint a few times during his campaign, including a Feb. 25 community forum at Woodside Church and the March 6 Democratic presidential debate at The Whiting Auditorium.

The Vermont Senator and Clinton have both called on Gov. Rick Snyder to resign over the water crisis. Snyder has said he will not resign and is resolute on fixing issues at the state level that led to the situation.

Clinton has also visited Flint, giving a speech on Feb. 7 at House of Prayer Missionary Baptist Church on the city's north end before meeting with local officials, including Flint Mayor Karen Weaver, U.S. Rep. Dan Kildee, D-Flint Township, Flint City Council President Kerry Nelson, and several others.

Some repairs have begun on lead-tainted lines in the city, with Weaver's Fast Start program using a $500,000 contract the state has with Rowe Professional Services to start infrastructure repairs.

The city also plans to use $2 million the state repaid Flint for reconnecting to back to Detroit's water system in 2015 to replace lines at an additional 200 homes.
