Biden wants Congress to take action on gun reform

The question of conviction is hardly a question at all. That makes it only a piece of a broader and more complex puzzle for the Republican Party as it seeks a new path in a post-Trump era that is far from rid of Trumpism.

The result of former President Donald Trump's impeachment trial this week seems certain, with perhaps only Trump's ability to restrain himself standing between him and a second acquittal in the Senate.

Still, the words and actions of the former president and some of his supporters up to and even after Jan. 6 have forced a GOP reckoning that has become louder and more contentious over the past month. It's convinced a growing minority of Republican elected officials that the party needs to be done with Trump once and for all.

As for Republican voters more broadly, Trump's hold on the party is strong but not total. The ABC News/Ipsos poll released Sunday found 15% of Republicans supporting Trump's conviction in the Senate -- not a huge number, but a substantial share given that Trump's approval rating inside his own party was well into the 90s for much of his presidency.

While Trump himself will not testify this week, his lawyers have made clear that he does not intend to convey regret over his actions -- or even to concede the falsity of his claims to have won the election.

Senate Republicans appear likely to keep general unity on the question of whether an impeachment trial for a former president is constitutionally appropriate. But even ending the trial won't come close to ending the Trump era for the Republican Party.

President Joe Biden released a statement Sunday night paying tribute to George P. Shultz, the 60th secretary of state, who died Saturday at age 100.

Shultz served three different presidents in his lifetime. In 1955, he served as a senior staff economist on President Dwight D. Eisenhower’s Council of Economic Advisers. In 1969, he was appointed to be secretary of labor by President Richard Nixon before serving as the first director of the Office of Management and Budget and then as the secretary of the treasury. Eventually, in 1982, he served as secretary of state for seven years under President Ronald Reagan.

“He was a gentleman of honor and ideas, dedicated to public service and respectful debate, even into his 100th year on Earth,” Biden said. “That’s why multiple presidents, of both political parties, sought his counsel. I regret that, as president, I will not be able to benefit from his wisdom, as have so many of my predecessors.”

Shultz celebrated his 100th birthday Dec. 13.

“He was a man of incredible courage,” Biden said. “Whether it was donning the uniform of the United States Marines to defend the cause of liberty in World War II, or speaking out directly to the President of the United States when he disagreed with a policy, George Shultz knew when to stand and fight. For the young women and men whose minds he helped shape throughout his career, there was no better role model for a life of integrity and service than George Shultz.”

Polling shows that while COVID-19 vaccine hesitancy is declining, it remains a partisan issue, FiveThirtyEight's Nate Silver said on ABC's "This Week."

A Kaiser health tracking poll released late last month showed that 47% of Americans have either already gotten the vaccine or will get it as soon as they can -- up from 34% in December. Still, 13% said they definitely won't get the vaccine and 7% said they'll get it only if required to for work, school or other activities. And 31% said they want to wait and see how it's working.

"It's also a highly partisan issue," Silver said. "While enthusiasm has increased among Democrats and independents, Republicans remain resistant. Thirty-three percent of GOP voters say they won't get the vaccine and will only get it if it's required."
