WASHINGTON (WFLA) – The U.S. Senate voted against calling additional witnesses in President Donald Trump’s impeachment trial on Friday.

Senators largely voted along party lines. Two Republicans – Sen. Susan Collins of Maine and Sen. Mitt Romney of Utah – voted with Democrats to call for additional witnesses. The final vote was 51-49.

Here’s how each senator voted:

Sen. Lamar Alexander (R-TN): No

Sen. Alexander, who is retiring at the end of his term this year and was considered a swing vote, released a statement late Thursday night to announce he would vote against calling additional witnesses.

“It was inappropriate for the president to ask a foreign leader to investigate his political opponent and to withhold United States aid to encourage that investigation,” Alexander said. “But the Constitution does not give the Senate the power to remove the president from office and ban him from this year’s ballot simply for actions that are inappropriate.”

Sen. Tammy Baldwin (D-WI): Yes

Sen. Baldwin voiced support for calling witnesses Friday morning when she tweeted a link to a New York Times report on former national security adviser John Bolton’s book. Bolton is one of the witnesses Democrats want to call to testify.

“Testimony and direct evidence from John Bolton would go to the heart of this impeachment trial- abuse of power and obstruction of Congress. The American people want the truth. John Bolton has it and the Senate cannot vote to ignore it,” Baldwin said.

Sen. John Barrasso (R-WY): No

During a news conference Thursday, Sen. Barrasso said it’s time to vote on impeachment.

“After about 120 questions, it seems to me that the House #impeachment managers have failed to make the case,” he said in a tweet.

Sen. Michael Bennet (D-CO): Yes

Sen. Bennet, who is running for president in 2020, tweeted Thursday night saying the Senate needs to demand witnesses and evidence.

“We do not live in a country where the president is above the law. And we can’t let them turn us into one,” he said. “We have to demand witnesses. We have to demand evidence. We have to demand a fair trial.”

Sen. Marsha Blackburn (R-TN): No

Sen. Blackburn tweeted a video message before the Senate convened on Friday saying she would vote no to calling more witnesses.

“It’s not the Senate’s responsibility to hold an impeachment do-over,” she said.

Sen. Richard Blumenthal (D-CT): Yes

Sen. Blumenthal tweeted a video message Thursday night criticizing Senate Republicans for opposing new witnesses and documents.

“As we ask our questions, Republicans sadly seem to be hardening their stance against witnesses & documents. Even as they complain about a lack of information, they are saying they don’t need any more facts. They cannot have it both ways,” he said.

Sen. Roy Blunt (R-MO): No

Sen. Blunt tweeted an audio clip of his appearance on a radio show Thursday saying, “House Democrats can’t bring a half-baked case to the Senate and expect us to make something of it. These are two of the weakest articles of impeachment you could possibly have.”

Sen. Cory Booker (D-NJ): Yes

Sen. Booker, who recently dropped out of the presidential race, tweeted Thursday night saying “we won’t stop voting for witnesses until the last vote is counted.”

“The truth is at our fingertips—it would be shameful if the Senate deliberately chose not to see it,” he added.

“Bolton is potentially a firsthand, corroborating witness to information that has been placed in evidence-based on his direct interactions with the president,” she said. “The decision the Senate must make is whether we hear from John Bolton now – testimony that may well have a determining factor in senators’ consideration of their votes – or if we postpone learning what he has to say until his book comes out in March.”

Sen. Deb Fischer (R-NE): No

Sen. Fischer released a statement Friday morning saying it’s time to vote on the articles of impeachment.

“Conducting an impeachment investigation is not the responsibility of the Senate, but the House.

Sen. Grassley has not released a statement about his decision.

Sen. Kamala Harris (D-CA): Yes

Sen. Harris, who dropped her presidential bid recently, was one of several Senate Democrats to hold a news conference Friday morning calling for witnesses.

Sen. John Kennedy (R-LA): No

Sen. Kennedy has not released an official statement on witnesses but did respond to Bolton’s book saying it didn’t answer the question of why President Trump asked for an investigation.

“I have said consistently for the past four months, since the Zelensky transcript was first released, that I believe that some of the president’s actions in this case – including asking a foreign country to investigate a potential political opponent and the delay of aid to Ukraine – were wrong and inappropriate. But I do not believe that the president’s actions rise to the level of removing a duly-elected president from office and taking him off the ballot in the middle of an election,” he said. “I also believe that processing additional witnesses will take weeks if not months, and it’s time for the House and Senate to get back to addressing the issues the American people are most concerned about.”
