“This year, there’s fewer than 30,” she continued.

Last week, a number of Democratic senators took to social media to share photos of a pile of hundreds of bipartisan House-passed bills that still await action in the Senate.

“This is the pile of House-passed bills, 90% bipartisan, dead on Mitch McConnell’s desk in the Senate #LegislativeGraveyard,” Sen.

The stack included several high-profile bills, like the Equality Act, the Violence Against Women Reauthorization Act and the Raise the Wage Act.

The demonstration came as a number of Democratic senators have continued to make jabs at McConnell — who has vowed to be the “Grim Reaper” when it comes to progressive policies in the Senate — over the pace of legislation in the chamber.

Republicans have sought to place blame over the stalled bills on what they call "impeachment obsession” as the House-launched investigation into President Trump Donald John TrumpBiden says voters should choose who nominates Supreme Court justice Trump, Biden will not shake hands at first debate due to COVID-19 Pelosi: Trump Supreme Court pick 'threatens' Affordable Care Act MORE has continued to dominate headlines.

“There are things that we have to do that ... we’re not making any progress on because of the impeachment obsession over in the House," McConnell told reporters last month. "I heard a number of Democrats in the House say they can walk and chew gum at the same time. Now is the time to prove it."

“The idea that the House impeachment inquiry is some sort of distraction from other issues is plain wrong,” he said in November, adding, “We have over 200 House-passed bills we could consider here on the floor, and plenty of bipartisan Senate bills.”
