Last week, we witnessed the reemergence of John Bolton, the president’s former national security adviser, and the release of his book. In it, Bolton describes his personal experiences with Donald Trump and his great alarm at Trump’s incompetence, his dangerous subordination of our national security to his own personal interests, and his fundamental indecency.

In short, Bolton is telling Americans what we already know. That the president is exactly what he appears to be: petty, self-serving, ignorant and utterly supplicant to autocrats in China, Turkey, North Korea and Russia.

We proved during the impeachment trial that Trump withheld hundreds of millions in military aid to Ukraine to coerce that country into announcing a sham investigation of his political rival. Bolton confirms our case and provides additional evidence of that flagrant abuse of power by providing a firsthand account of how Trump confirmed this illicit quid pro quo during a conversation they had. Moreover, Bolton also corroborates the testimony of Gordon Sondland, the former U.S. ambassador to the European Union who testified that “everyone was in the loop.” Indeed they were, including the secretary of State, the Defense secretary and Attorney General William Barr.

But Bolton does more than just confirm the impeachment charges. During the trial, I raised a hypothetical question about China intervening in our election and whether Trump would resist such interference — or offer China a better trade deal, instead. As it turns out, this was no hypothetical. Bolton details how Trump sought reelection help from China, at one point begging Chinese President Xi Jinping for assistance and apparently offering trade concessions to get it.

According to Bolton, Trump also undermined the values of our country by telling Xi that not only was it appropriate for the Chinese leader to imprison millions of Uighurs in detention camps, but also that it was the right thing to do. This is a stunning betrayal of everything America stands for and can only be understood in the context of Trump’s desperation to secure China’s help for his reelection.

No wonder, too, that while a new virus was threatening the health of our citizens, President Trump continued singing China’s praises while knowing that China was concealing important information about the virus’ spread.
