Democrats avoided using the "I" word during the national convention this week. Over the course of four nights, party members blasted the President as a genuine threat to democracy and urged voters to support Joe Biden if they want a leader who can provide a steady hand in confronting the multiple crises that face our country.

Remember how President Donald Trump used to say, "No collusion," at every chance, to stave off -- among other things -- impeachment? He's now using a similar craft-a-narrative tactic, this time hoping it will help him stay in office: He blasts mail-in voting incessantly.

Lt. Col. Alexander Vindman, a key witness in President Donald Trump's impeachment inquiry, is retiring from the US Army after more than 21 years of military service because he determined that his future in the armed forces "will forever be limited" due to political retaliation by the President and his allies, his lawyer told CNN Wednesday.

Declaring in 2016 that "I alone can fix it," Donald Trump made the country's fate all about him. He promised so much "winning" we'd get sick of it, and asked "What have you got to lose?" As President he made everything into a fight between Team Trump (good) and everyone else (bad). He bullied those he couldn't persuade and even survived an impeachment trial. But now, confronted with a pandemic, an economic crisis, and a moment of reckoning over racism, the limit of the president's method is obvious, and he seems on the brink of becoming the thing he most dreads: A loser.

John Bolton pushes back after CNN's Wolf Blitzer suggests that Bolton "might've made a difference" if he had testified against President Trump during the impeachment trial.

Special counsel Robert Mueller examined whether President Donald Trump lied to him in written answers during the Russia investigation, a possibility House Democrats have said they continue to look into even after Trump's impeachment.

During an interview with CNN's Erin Burnett, lead House impeachment manager Rep. Adam Schiff (D-CA) responds to former national security adviser John Bolton's accusation in his new book that Democrats committed "impeachment malpractice."

Senate Republicans are unmoved by the stunning allegations in former national security adviser John Bolton's forthcoming book, saying Bolton's accusation that President Donald Trump sought reelection help from Chinese President Xi Jinping did not change their minds against calling him as a witness in the impeachment trial.
