Nancy Pelosi stated the following:
“That doesn't matter. That doesn't matter. Because we cannot have a president of the United States undermining his oath of office, his loyalty to his oath of office, undermining our national security, and undermining the integrity of our elections.”
By this Speaker of the House Pelosi is saying that the political ramifications for impeachment (losing the House in 2020) are worth getting the President impeached. This means that Pelosi is willing to get Trump impeached at all costs, her support for impeachment is already going to cause major political losses in the opinion of most experts.
