If you really believe this hogwash from Sasse, nothing any of us will say will change your mind.
Trump did not listen to "bad advice" and certainly never took counsel from better advisors.
Trump actively and purposefully directed his personal lawyer and that lawyer's cronies (who have since been indicted) to coerce an ally (Ukraine) to announce corrupt political investigations into an American citizen who just happened to be the main Democratic party contender running against Trump in the 2020 election.
When that effort stalled and then Ukraine elected a reformist PM focused on rooting out corruption who decided not to play ball with this obviously corrupt activity, Trump directed his lawyer and cronies to manufacture a smear campaign against the US ambassador in Ukraine to get her out of the way.
When the new PM still resisted their corrupt conduct, Trump directed his EU ambassador, the Secretary of Energy, the VP, the special envoy to Ukraine and, yes, again his personal lawyer and cronies to use taxpayer funded and congressionally allocated military aid and a white house visit as leverage to get compliance.
Eventually, the new PM who depended on US military aid in their ongoing fight against Russian invasion and had tried every way to avoid engaging in this corrupt conduct, relented and had scheduled the interview with Fareed Zakaria on CNN to publicly announce the investigations into the Bidens and the Russian propaganda that Ukraine, not Russia, had interfered in the 2016 US elections and on the behalf of Clinton, not Trump.
Then Trump and his cronies got caught, it came out publicly and he hurriedly released the military aid and covered up the conduct in every way possible with complicity from his administration - Pence, Pompeo, Barr, Perry and all the rest including, yes, his personal lawyer and cronies.
Ben Sasse and every other Republican knows all these facts because the House managers, law enforcement, intelligence community and media uncovered the evidence to prove it despite historic obstruction of justice by Trump and his administration and the Republicans in Congress.
Sasse, like all the other Republican sycophants, will eventually pay the price for their cover-up and complicity. All they are thinking about is 2020 and getting Trump re-elected so they can continue to stay in power, line their pockets and move forward with their destructive policies for the middle and working classes, the poor, people of color, muslims, immigrants, women, the LGBT community and any one else who dares challenge their fascist and xenophobic agenda.
If you are a white Christian straight wealthy male over age 40 or someone who declares fealty to Trump, you're fine. Everyone else is fair game. You've been warned. Do not test us or we will crush you. Shut up and be grateful for what we have decided to allow you to keep.
