WATCH: Michael Flynn's sister sings 'God Bless America' at pro-Trump rally — and struggles to remember the words

At Saturday's Washington, D.C. rally of Trump supporters protesting the results of the election, former National Security Adviser Michael Flynn took the stage, fresh off his pardon from the president and accompanied by his sister Barbara Redgate.

During the appearance, Redgate took the microphone and sang "God Bless America" to the crowd — although commenters on social media noticed that she appeared to struggle to remember the words.
