Though Graham has ridiculed the case against the Republican president and heaped scorn on Democrats like Schiff, he said he believes the California Democrat is "well spoken" and "did a good job of creating a tapestry..."
Each side was given 24 hours over three days for their arguments.
"You can't just go home early because you're bored", he says.
House lawyer Douglas Letter argued in two letters Thursday that the Trump legal team's arguments during the impeachment trial had changed the game.
Trump, who is intensely focused on media coverage and its effect on public opinion, has tried to counterprogram this week's impeachment proceedings. Our coverage continues on Friday at 12:50 p.m. ET with politics reporter Evan Donovan and DC correspondent Jessi Turnure.
The notion that a Trump apology over his call, accompanied by grave-faced GOP officials decrying the act but begging that Trump be given a second chance, would have led to Democrats backing down on their impeachment push is pure fantasy. Graham said. "That's becoming relevant because they talked about it nearly 50 times that the president had no reason to believe that anything improper occurred in the Ukraine with the Bidens".
He spent two days at the World Economic Forum in Davos, Switzerland, returning on Wednesday night after firing off a 142 tweets and retweets, a personal record for the president, mostly about the impeachment.
Republicans say they're not hearing anything new, and Democrats are slamming them for voting against bringing in new documents and witnesses.
"The reason that Bolton is an important witness is that the Senate majority has pre-judged the case and indicated that they will not vote to remove President Trump", said Barb McQuade, a former federal prosecutor and law professor at the University of MI. Donald Trump's threat to assert executive privilege in his impeachment defense to try to curb testimony by his former national security adviser John Bolton is an attempt to silence a key witness and could undermine constitutional principles, ex-justice department officials and legal scholars warn.

We're not going to run out the clock", he said. In a tweet Friday, he complained about the Saturday morning opening slot for his lawyers, although the schedule was set by Senate Majority Leader Mitch McConnell (R-Ky.). But the Democratic managers may have alienated the few moderate Republicans, who've yet to decide whether they need more evidence, by giving what GOP senators have characterized as repetitive and lengthy arguments.
Finally, Colbert noted that Trump "fan-boy" Matt Gaetz was left off the president's impeachment defense team, perhaps because the Florida Republican congressman dared support a recent resolution to rein in the president's war powers.
Certainly, it's been draining for the 100 senators who had to sit more than 12 hours at a time silently listening to the prosecution, known as the House managers, make their case. Do they think it would satiate Resistance Democrats who have been calling for Trump's impeachment and removal since November 2016? Then they will again tussle over whether to introduce new witnesses.
About 7 in 10 said so, including majorities of Republicans and Democrats, according to the poll.
Only the most rabid partisan would find that convincing in the least-the sort of partisan who would take any admission by Senate Republicans of Trump's wrongdoing as proof positive that he must be removed from office, niceties about what constitutes an impeachable offense be damned.
