Sen. Ben Sasse (R-Neb.) said Tuesday that President Trump's remarks at his summit with Russian President Vladimir Putin marked a "bad day for America."

He told Dana Perino that there's no moral equivalency between Trump and Putin, so when Trump was on the world stage he had the opportunity to explain how America is different.

Trump has received backlash from both sides of the aisle for touting Putin's denial that Russia meddled in the 2016 election.

The president on Tuesday clarified his comments, saying that he misspoke.

Sasse said on "The Daily Briefing with Dana Perino" that Trump failed to communicate American values.

"There's no difficulty. This isn't complicated in explaining who we are and who Putin is," he said. "That's what needed to happen yesterday."

Sasse went on to call Putin a "thug" who attacked America through election meddling.

He said it isn't a bad thing for Trump to meet with foreign leaders with whom he doesn't necessarily always agree, but that he must be strong.

"You start by explaining who we are and what we believe. Man, we were weak yesterday on the global stage," he said.
