Congress convened a joint session on January 6-7, 2021, to count electoral votes by state and confirm the results of the 2020 presidential election. Harris voted against certifying the electoral votes from Arizona and Pennsylvania. The House rejected both objections by a vote of 121-303 for Arizona and 138-282 for Pennsylvania.

Harris, a medical doctor, was credited with helping to save the life of a two-year-old along the side of highway Route 50 on August 26, 2012.

In April 2009, Harris prevented the University of Maryland, College Park (UMCP) from holding an on-campus screening of the film Pirates II: Stagnetti's Revenge, which some called pornographic. The original version had a self-applied X-rating, but the film was later edited to qualify for an R-rating from the Motion Picture Association of America. As part of the showing in the student union, UMCP organizers planned to have a safe sex discussion with a representative from Planned Parenthood. Administration officials canceled the film after Harris threatened to cut the university's budget. “ We can't be spending taxpayers' dollars for the screening of pornographic materials on campuses. That's not good policy. ” —Andrew Harris The board of regents refused Harris' request for the university to adopt a policy on obscene material. Lawmakers gave the university a December 1 deadline to come up with policies on showing obscene materials, but student representatives on the board voted down an adoption of such a policy. “ The establishment of any policy would effectively say it is acceptable for state politicians to dictate that the university system fall in line with their political agendas. This is irresponsible and puts the system's 143,000 students at a severe disadvantage compared to their peer institutions. ” —Steve Glickman and Sarah Elfreth
