Rep. Rashida Tlaib (D-MI) came to Congress dressed in traditional Palestinian clothing.
Ms Tlaib, a Detroit native whose family hails from a small Palestinian village in the West Bank, was sworn into the 116th Congress using Thomas Jefferson's copy of the Quran, translated into English in 1734.
"And when your son looks at you and says, 'Mama look, you won. Bullies don't win", her son said, according to her.
Newly minted House Speaker Nancy Pelosi (D-CA) said on the Today Show Thursday that it could depend on the results of the special counsel's investigation into the Trump campaign's ties to Russian Federation. "Our leaders are stupid, they are stupid people", Trump said of the Obama administration, the magazine reported.
Tlaib was unapologetic Friday morning, penning an op-ed to back up her call for impeachment.
Under the Constitution, presidents can be impeached and removed from office for "treason, bribery, or other high crimes and misdemeanours".
"More to the point, I disagree with what she said".
"I believe in secular government (and) my swearing in on the Koran is about me showing that the American people are made up of diverse backgrounds and we all have love of justice and freedom", she said.
Another pro-Republican account claimed Tlaib's comments actually help Republicans, not Democrats.
Ms Omar arrived to Congress accompanied by her father and wearing a Hijab.
The impeachment process would further require the consent of both the House and two-thirds of the Senate, which is still a Republican majority. They also ignore the fact that numerous impeachable offenses committed by this president are beyond the scope of the special counsel's investigation.
"I think some of our new members probably don't realize that you are always on, that when you are a member of Congress, there's always someone listening", said Rep. Jan Schakowsky, D-Ill.
In the speech, Trump ripped lawmakers, describing them as "bloodsuckers", and slammed Obama.
