And yet the budget went up every single year throughout Reagan's term (table below from linked pdf).
The son's sister : "He wasn't too happy the last years of his life, working for Reagan. He was pretty messed up about it."
Steve Coogan's character : "The Republicans withdrew funding for AIDS research because they blamed the epidemic on the gay lifestyle."
Update (Nov 12, 2017; nearly a year and a half later LOL) : It dawned on me that Congress appropriates funding. Hmmm, who was in charge of Congress?
When Reagan took office House 244 (D) to 191 (R), Senate 46 (D) to 53 (R) and one independent
1983-85 House 272 (D) to 163 (R), Senate 45 (D) to 55 (R)
1985-87 House 253 (D) to 182 (R), Senate 47 (D) to 53 (R)
1987-89 House 258 (D) to 177 (R), Senate 47 (D) to 53 (R)
The final weeks of the Reagan administration : House 251 (D) to 183 (R), Senate 55 (D) to 45 (R)
So throughout Reagan's term, the Republicans never were even close to a majority in the House and except for the very end where they became a minority they had a slight majority in the Senate but at no point had a filibuster proof majority.
