There is a Speaker of the House, just not a permanent one. The house can function today as it did three weeks ago. That is..it can barely function.
I haven’t seen any person suggest that the US get involved beyond giving them arms support and intelligence.
And that is the problem, we are at war. Americans have been massacred, taken hostage, abused, and killed. That is not something we leave for someone else to address. That is our problem. Biden and Harris need to call for a declaration of war. They won't. The House should issue and pass a declaration of war. Islamic Cult and Iran-back, Biden and Harris funded Hamas attacked the US, has and is killing Americans, holding them hostage. Declare the obvious war we are in and prosecute it without mercy.
