I suggest you look into it further. That is EXACTLY what GM did. They borrowed money from the TARP fund to pay back the initial government loan. GM has paid NOTHING back yet.
you should really stop getting your information from Fox News.
"Because most of the $50 billion G.M. received was
converted to an equity stake held by the Treasury Department, Mr. Akerson said G.M. had “technically” repaid its debt to the government, but he added that executives were “doing our level best” to help taxpayers recoup the remaining amount. The Treasury, which still owns 26 percent of G.M., has recovered about half of its investment in G.M."

conversion of loans to an equity share is not borrowing from the government to pay back the government.
this is also directly from your Forbes article:
Because a loan of such a huge amount would have been politically controversial,
the Obama administration handed GM only $6.7 billion as a pure loan. (It asked for only a 7% interest rate--a very sweet deal considering that GM bonds at that time were trading below junk level.) The vast bulk of the bailout money was transferred to GM through the purchase of 60.8% equity stake in the company--arguably an even worse deal for taxpayers than the loan, given that the equity position requires them to bear the risk of the investment without any guaranteed return. (The Canadian government likewise gave GM $1.4 billion as a pure loan, and another $8.1 billion for an 11.7% equity stake. The U.S. and Canadian government together own 72.5% of the company.)
