McGahn served as Donald Trump's campaign counsel during his 2016 campaign for president. McGahn managed all litigation involving Donald Trump's 2016 Presidential campaign. Early in 2016, he stopped efforts to keep Trump off of the Republican primary ballot in New Hampshire by going to court and winning to ensure ballot access in a key primary state. Several weeks before the election, lawsuits were filed in four battleground states alleging voter intimidation and seeking to enjoin the Trump campaign from having observers at polling locations. McGahn successfully managed and won these litigations.
