The president has a brother the brother dose not have a brother how is this possible?

Sry after the first brother it's suppose to have a comma and say but that brother has no brother

There step brothers?

the president is a woman.

How?

The situation you described is a bit unusual, but it is possible due to a few different scenarios:

1. Adoption: The president and their brother may not be biological siblings. If the brother was adopted into the family, he might not have any biological brothers, but the president could still have other siblings who are related by blood.

2. Half-Brother: The president and their brother could have different biological fathers. In this case, the brother would not have a brother from his father's side, but the president could have a brother if they share the same father.

3. Step-Brother: The president and their brother might not be related by blood at all. If their parents divorced or remarried, the president could have a step-brother from their mother's or father's new marriage, while the brother would not.

Keep in mind that without more information or context, it is difficult to provide an exact answer to this riddle-like question.
