Joe Walsh, an outspoken Trump supporter throughout his campaign, tweeted his disappointment in response to top Trump adviser Kellyanne Conway’s defense of the president-elect's dismissive response.

“I’m a Trump supporter @KellyannePolls, but there’s no defense 4 his horrible reaction to this Russian scandal. None,” Walsh tweeted.

Trump slammed the report, first reported by The Washington Post Friday, that concluded Russia intervened in the 2016 election in an interview with Fox News on Sunday.

“I think it’s ridiculous,” Trump said. “I think it’s just another excuse. I don’t believe it.”

Walsh made waves throughout the election for his controversial tweets made in Trump’s support. In October, Walsh tweeted that "if Trump loses, I'm grabbing my musket."

On November 8th, I'm voting for Trump.

In July, Walsh posted, then later deleted, a tweet several Democratic lawmakers saw as threatening.

“3 Dallas cops killed 7 wounded. This is now war. Watch out Obama. Watch out black lives matter punks. Real America is coming for you,” he wrote.

Walsh represented Illinois's 8th Congressional District for one term, from 2011 to 2013.
