(CNN) Freshman Democratic Rep. Rashida Tlaib has formally submitted her impeachment resolution Wednesday afternoon with only one other member's name of support — Democratic Rep. Al Green of Texas, who has tried to push the impeachment issue on his own before.

"Just Al Green and I," Tlaib said, adding that she does not think there will be any others who come forward with their support.

Tlaib has been working behind-the-scenes to get colleagues to put their name on the resolution that directs the House Judiciary Committee to inquire whether President Donald Trump committed impeachable offenses.

Earlier this week she sent a "Dear Colleague" letter to a targeted list of members who in the past had shown an openness to pushing for impeachment and that she thought could be open to signing their name to her resolution.
