President Donald Trump’s political operation is launching a multimillion-dollar legal campaign aimed at blocking Democrats from drastically changing voting rules in response to the coronavirus outbreak.

In the past several weeks, the reelection campaign and the Republican National Committee have helped to oversee maneuvering in a handful of battleground states with an eye toward stopping some Democratic efforts to alter voting laws, and to bolster Trump. The mobilization is being closely coordinated with Republicans at the state and local levels.

The Trump campaign and RNC are actively engaged in litigation in Wisconsin, where the parties are at loggerheads over an array of issues including voter identification, and in New Mexico, where the battle involves vote-by-mail. The skirmishing has also spread across key states like Pennsylvania and Georgia, where the well-organized Trump apparatus has fought over changes that could sway the outcome of the election.
