Alice, who lives in state B, owes Henry, who lives in state A, $2,000. He wants to sue her to collect the money. He wants to sue in a federal district court. He is afraid that if he brings suit in state A, the courts of that state will be prejudiced against him because Alice is a woman. He is afraid that if he sues in the courts of state B, those courts will be prejudiced because he is a "foreigner." Can Henry sue Alice in a federal district court
