In an uncharacteristic move on social media, President Donald Trump used his personal Twitter account, @realDonaldTrump, to like a Fox Nation tweet Wednesday about a story with the headline 'Franken Says He Thinks Sessions Committed Perjury.'

The article linked to the tweet liked by the president is about Sen. Al Franken's comments on Attorney General Jeff Sessions, following the Senate Judiciary Committee hearing Tuesday. Sessions was asked to appear before the committee to clarify an answer he gave in January about meetings with Russian officials while under oath during his confirmation hearings. Franken on Tuesday said Sessions “perjured himself.”

The controversy around Sessions began last week after a Washington Post article Wednesday claimed he held a meeting with Sergey Kislyak, the Russian ambassador to the U.S., between July and September 2016, while he was an Alabama senator. Following the release of the article, Democrats began calling for Sessions' resignation. Sessions admitted Thursday (after initially denying) he had meet with the ambassador, but added he had taken no action on any investigation-related matters.

"When you evaluate the rules I feel like I am — I should not get involved investigating a campaign I had a role in," CBS News quoted him as saying. He also recused himself last week from any investigation involving the presidential campaign.

“My answer was correct,” Sessions wrote in a letter to Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa) on Tuesday. “I was surprised by the allegations in the question, which I had not heard before. I answered the question, which asked about a ‘continuing exchange of information during the campaign between Trump’s surrogates and intermediaries for the Russian government,’ honestly.”

“I did not mention communications I had had with the Russian ambassador over the years because the question did not ask about them."

However, Sessions’ defense was considered inadequate by Franken who reacted by saying: "That's a ridiculous response. It's not a clarification at all."

Considering that Trump defended Sessions vigorously on Twitter after the latter recused himself last week, the president liking the Fox News tweet is very peculiar.
