They argued that both the articles of impeachment are “legally flawed and factually insufficient, as well as inherently destructive of separation of powers, the Senate should explicitly reject them to protect both the institution of the Presidency and the Constitution.”
They continued:
This partisan political effort undermines the democratic process, both now and in the future. The House unilaterally re-writes the constitution, without the people’s consent to amend it. It weaponizes a process that should only be initiated in exceedingly rare circumstances and never for partisan purposes. This purely partisan attack on President Trump will damage democracy in America in the worst possible way: it will forever weaken the separation of powers–the very edifice upon which our democracy stands.
