On the last day of August, the Fox News host Laura Ingraham interviewed President Trump on her show, “The Ingraham Angle.” Five weeks earlier, Trump endured a half-hour interview with the Axios political reporter Jonathan Swan, who grilled Trump about Covid-19 with the kind of disdain economics professors reserve for a graduate student who botches the calculation. Ingraham was the anti-Swan, fawning and pat. Leaning forward in her chair with a warm expression, she tossed softballs and gently guided the president back on track when he veered into politically risky territory.
