  Donald Trump has tweeted thousands of times during his presidency. These
public statements are an increasingly important way through which Trump
communicates his political and personal views. A better understanding of the
way the American public consumes and responds to these tweets is therefore
critical. In the present work, we address both consumption of and response to
Trump's tweets by studying replies to them on Twitter. With respect to
response, we find that a small number of older, white, left-leaning, and female
Americans are responsible for the vast majority of replies to Trump's tweets.
These individuals also attend to a broader range of Trump's tweets than the
rest of the individuals we study. With respect to consumption, we note that
Trump's tweets are often viewed not in isolation, but rather in the context of
a set of algorithmically-curated replies. These replies may therefore color the
way Americans consume Trump's tweets. To this end, we find some evidence that
Twitter accounts see replies in line with their political leanings. However, we
show that this can be largely, although not entirely, attributed to the fact
that Twitter is more likely to show replies by accounts a user follows. As a
basis for comparison, all results for Trump are compared and contrasted with
replies to Joe Biden's tweets.
