WASHINGTON, D.C. — U.S. Rep. Lloyd Doggett, D-Austin, has joined some 50 House Democrats — including two others from Texas — who will not be attending President-elect Trump’s inauguration on Friday as the 45th president of the United States.

"We are sending a message to Mr. Trump. Respect, like Pennsylvania Avenue, is a two-way street," Doggett said in a tweet Tuesday afternoon. "Instead of uniting our country, his continued unprecedented, unpresidential actions are further dividing it. By repeatedly taking the lowest road, he is not showing respect for the highest office. We are in for a long struggle that must strategically utilize every nonviolent opposition tool available."

Doggett is the third Texas Democrat to say he will not be attending the Trump inaugural to express their disapproval of Trump’s behavior.

"I will not attend the inauguration because conscience says it is the right thing to do," U.S. Rep. Al Green, D-Houston, said in a statement.

"Every American should respect the office of the presidency and the fact that Donald Trump will be the 45th President of the United States," U.S. Rep. Joaquin Castro, D-San Antonio, said in a statement. "But winning an election does not mean a man can show contempt for millions of Americans and then expect those very people to celebrate him."

U.S. Rep. Barbara Lee, D-California, last Thursday was the first member of Congress to say she wouldn’t be attending the inauguration because, she said in a statement, "Donald Trump has proven that his administration will normalize the most extreme fringes of the Republican Party. On Inauguration Day, I will not be celebrating. I will be organizing and preparing for resistance."

The boycott really gained steam after U.S. Rep. John Lewis, the Georgia Democratic, who as a young man played a heroic role in the Civil Rights Movement, told Chuck Todd in an interview for "Meet the Press" that he could not attend the inauguration because, "I don’t see the president-elect as a legitimate president."

"I think the Russians participated in helping this man get elected. And they helped destroy the candidacy of Hillary Clinton," Lewis said.

But, what really sparked outrage among Democrats was Trump’s reply to Lewis.

In two tweets, the president-elect said, "Congressman John Lewis should spend more time on fixing and helping his district, which is in horrible shape and falling apart (not to……mention crime infested) rather than falsely complaining about the election results. All talk, talk, talk — no action or results. Sad!"
