Rep. Doug Collins of Georgia said he would introduce the resolution earlier this week, saying that “it’s clear that Nancy Pelosi does not have the mental fitness to serve as Speaker of the House of Representatives.”…

“Nancy Pelosi’s unwillingness to abide by the Constitution, combined with her recent actions, call into question her own mental fitness. It’s critical that the House of Representatives demand her removal from the line of succession,” Mr. Collins wrote on Twitter.

“Combined with her recent actions” is likely a reference to Mrs. Pelosi announcing last week while President Trump was ill that she wants a “bipartisan” commission that could remove a mentally-unfit president under the 25th Amendment.
