Alleged ties between the Muslim Brotherhood and the family of Democratic Michigan Senate candidate Abdul El-Sayed are facing increased scrutiny following the candidate's interview Sunday on NBC's "Meet the Press." 

NBC White House correspondent Kristen Welker asked El-Sayed about allegations his family has connections to the Islamic group. El-Sayed denied any such connections twice in the interview with one-word responses. Welker asked no follow-up questions on the issue and moved on to other issues. 

However, the Washington Beacon reported that El-Sayed's mother was active in the Muslim Brotherhood while she attended college in Egypt, the Washington Free Beacon reported. 

Eman Abdelhadi, a University of Chicago professor and El-Sayed’s half-sister, posted comments on X about her mother and other family members' ties to the Islamic group in June 2012, shortly after Muslim Brotherhood leader Mohamed Morsi was elected president of Egypt.

"Had an amazing talk with my mom about her activism in the Muslim Brotherhood during the early 70s while she was in college," Abdelhadi said in one post. In another post, she stated that her family has "long been" associated with the group. 

In his book, "Healing Politics," El-Sayed wrote about his mother's campus activism but made no mention of any association with the Muslim Brotherhood.
