President Donald Trump spent the early part of his St. Patrick's Day on Twitter, taking aim at the late Sen. John McCain, Fox News, "Saturday Night Live," and GM.

Trump started the morning by slamming "Saturday Night Live" for its repeated jokes about his presidency, even calling in two tweets for federal regulation of the comedy show.

Trump also attacked the late Republican Sen. John McCain, writing that McCain was "last in his class" and accusing him of giving the FBI and multiple media outlets an unverified dossier detailing ties between Trump and Russia.

President Donald Trump spent the early part of his St. Patrick's Day making waves on Twitter, taking aim at numerous people and some issues he had also sounded off on the day before.

Trump started Sunday morning by slamming "Saturday Night Live" for its repeated jokes about his presidency, in two tweets calling for federal regulation of the comedy show.

The show had aired a rerun the night before featuring a sketch imagining what life would be like if he had never become president.

Trump lamented that "SNL" and other late-night shows "can spend all of their time knocking the same person (me), over & over, without so much of a mention of 'the other side'" in what he called "an advertisement without consequences."

Trump also targeted the late Republican Sen. John McCain on Twitter for the second time in two days nearly seven months after the senator's death, writing that was McCain "last in his class" and accusing him of providing the FBI and multiple media outlets with the unverified dossier detailing ties between Trump and Russia.

The tweets earned Trump his second hit back from the senator's eldest daughter, Meghan, who quoted Trump's tweet and added: "My father lives rent free in your head."

Trump's feed wasn't without some St. Patrick's Day cheer, as he shared a picture of his receiving shamrocks from Irish Prime Minister Leo Varadkar.

But Trump too responded to Fox News' announcement that it was canceling a new episode of "Justice with Judge Jeanine" over its host Jeanine Pirro's suggestion a week earlier that Rep. Ilhan Omar wearing a hijab was "antithetical to the United States Constitution."

Trump in part mentioned a conspiratorial idea that the "Radical Left Democrats" were working together to "silence a majority of our country" by affecting conservative media.

"We're not commenting on internal scheduling matters," a Fox News representative told INSIDER.

The president continued his tear by calling on a United Auto Workers union leader to "get his act together and produce" and saying that General Motors "let our Country down" by shutting down a plant in Lordstown, Ohio, where it made the Chevy Cruze.

"I want action on Lordstown fast," he wrote. "Stop complaining and get the job done!"

The tweet calling out David Green, the president of United Auto Workers Local 1112, appeared to be an advance on his tweeted demand the day before, in which he urged, "Time is of the essence!"
