The correct answers are
A. Florida Lt. Governor Carlos Lopez-Cantera had his bar mitzvah at the Western Wall in 2016, at the age of 42. Lopez-Cantera, whose official bio lists his religion as Catholic, had recently announced that he is in fact Jewish, saying, “My father came from Cuba but he married a nice Jewish girl in Miami.”
and
B. In an interview following a sketch he did with Andy Samberg on Saturday Night Live, singer Michael Bolton said, “I’ve been kicked out of every class. Andy and I were talking about that. Neither one of us had our Bar Mitzvah because we couldn’t take Hebrew school seriously.” However, when Bolton, age 62, made a trip to Israel in 2015, he spontaneously decided to make a bar mitzvah at the Wall after meeting Rabbi Shmuli Weiss, who helped Bolton don tefillin for the first time.
and
D. Actor Jeremy Piven celebrated his bar mitzvah when he was 13, though he says he was not a good student. “It was hard for me to learn Hebrew. I actually had to rap my haftorah portion.” In 2016, Piven celebrated his second bar mitzvah on a balcony overlooking the Western Wall. After the ceremony he sang “Siman tov u’mazal tov” with NBA players Omri Casspi and Amar’e Stoudemire.
