Depends on the situation. The runner who is in jeopardy of being tagged out is the runner who does not have legal rights to the base.

In a force situation, the runner with legal right to the base is the following runner, so the lead runner would be out if tagged.

In a non-force situation, the lead runner has legal right to the base and the following runner will be out if tagged.

If the force is removed while the 2 runners are standing on the base, the runner that has legal rights to the base changes.
