• Senator Klobuchar received the support of conservatives after seemingly showing support for President Trump
  • In a tweet, the Democratic senator said the president should nominate the Justice
  • Donald Trump Jr., the president's eldest son, thanked Klobuchar for her support

Sen. Amy Klobuchar, D-Minn., is the subject of backlash after Donald Trump Jr. thanked her for a tweet where she seemingly argued that the current president should replace the late Justice Ruth Bader Ginsburg, Fox News reported.

Capitol Hill has been locked in an ongoing battle over whether the Senate should fill the vacant Supreme Court seat following the passing of Justice Ginsburg on Friday, just weeks before the 2020 presidential election.

Klobuchar, who ran for the Democratic presidential nomination, took to Twitter to weigh in on the argument. "The people pick the President; the President nominates the Justice. That is how it works," Klobuchar wrote.

Her tweet received the support of many conservatives, including Trump campaign rapid response director Andrew Clark and the president’s eldest son Donald Trump Jr.

"I agree and @realDonaldTrump is the President," Trump Jr. tweeted. "Glad to have your support on this Amy."

Klobuchar, who is a member of the Senate Judiciary Committee, published another tweet an hour later where she said the president who wins the 2020 election should be the one to pick the next Supreme Court justice.

On Sunday, the Democratic senator appeared on CNN’s “State of the Union” and urged her Republican colleagues to block a vote on any appointee nominee by Trump the same way they blocked former President Barack Obama’s Supreme Court nominee in 2016.

“They set this precedent, they can’t mess around and use raw political power right in the middle of an election,” she said of the GOP’s 2016 decision.

According to CBS News, Klobuchar also called on Republicans to respect Ginsburg’s last wish, which she dictated to her granddaughter.

"My most fervent wish is that I will not be replaced until a new president is installed," Ginsburg said.

Republican senators Susan Collins of Maine and Lisa Murkowski of Alaska have said that they oppose filling the empty Supreme Court seat before the forthcoming presidential election, which is now 50 days away. However, others walked back on what they said in 2016.

Republicans would need 51 votes to appoint a nominee. They currently have a 53-47 majority in the Senate. If all 47 members of the Senate Democratic oppose Trump’s pick, Republicans could not afford to lose more than three defections, The Hill reported.
