In the first year of his second term, President Trump has cited an arsenal of falsehoods, baseless claims and distortions to justify significant policy changes on the economy, immigration and deployments of the military. His case for ushering in a turnaround rests on inaccurate superlatives (the "worst inflation" ever under his predecessor and the "best numbers" now under his presidency), mathematically impossible figures (a "600 percent" decline in drug prices) and evidence-free assertions (the decimation of maritime drug smuggling).
