A delayed reopening of a Canada–US bridge connecting Michigan and Canada has become an issue in the closely watched Michigan Senate race. Democratic candidate Mallory McMorrow is highlighting the delay and accusing President Donald Trump and Republicans of keeping the bridge closed to benefit a political donor, according to reporting carried by the Associated Press. McMorrow has launched what she describes as her first major push to frame the controversy as a potential political liability for Trump and the GOP, including a new campaign advertisement released this week. The coverage notes that the bridge delay, which has drawn public attention on both sides of the border, is now being used in campaign messaging. Other details about the specific donor or the reasons for the delay are not included in the provided excerpts. The allegations are presented as part of McMorrow’s campaign strategy in the Senate contest, while the underlying situation involves officials’ decision-making over the timing of the bridge’s opening.
