I'm curious, did anyone here actually read any of the letters linked in the op? I went through them and no where did I see Ryan say what Biden claims: “I love that. I love that. This was such a bad program and he writes me a letter saying — writes the Department of Energy a letter saying, “The reason we need this stimulus, it will create growth and jobs.” His words. And now he’s sitting here looking at me."
The closest thing that I could find which resembles Biden's claim is: "I was pleased to learn that their Topic Area 1 project is aimed at transforming energy efficiency retrofit markets, building sustainable demand for green jobs, and providing a model in other communities." Aka, "Their plan is aimed at creating a demand for jobs, among other things."
The letters appear to be just what Ryan said they were, him advocating stimulus money for his constituents. All the letters are pretty much the same too; "Company X wants money for project Y and they believe this will result in Z. I have reviewed their plan, and agree that it is deserving of money, please give them some."
In a way, it kind of shows that Biden fibbed a little. "His words", as claimed by Biden, were not "His words", but an inaccurate paraphrase of "His words" Now, that is just in the letters linked and does not include other letters that were not linked or videos.
