  This study verified the effectiveness of Donald Trump's Twitter campaign in
guiding agen-da-setting and deflecting political risk and examined Trump's
Twitter communication strategy and explores the communication effects of his
tweet content during Covid-19 pandemic. We collected all tweets posted by Trump
on the Twitter platform from January 1, 2020 to December 31, 2020.We used
Ordinary Least Squares (OLS) regression analysis with a fixed effects model to
analyze the existence of the Twitter strategy. The correlation between the
number of con-firmed daily Covid-19 diagnoses and the number of particular
thematic tweets was investigated using time series analysis. Empirical analysis
revealed Twitter's strategy is used to divert public attention from negative
Covid-19 reports during the epidemic, and it posts a powerful political
communication effect on Twitter. However, findings suggest that Trump did not
use false claims to divert political risk and shape public opinion.
