of course he would, he's an imperialist scumbag like the rest of them

Every day:

• The Pentagon unveils $1.3 billion for Ukraine, bringing total new U.S. aid this week to $2.3 billion.
• US to provide $345 million in military aid for Taiwan
• US Senate approves $12bn for Ukraine in government funding bill

Every other day:

• student loan relief shot down
• budget accountability shot down
• tax enforcement on top income earners shot down
• funding to medicare slashed
• funding for food assistance programs slashed
• funding for school lunch programs slashed
• funding for public schooling slashed
• union strikes shut down
• tax relief and subsidies increased for most profitable companies
• tax relief for most wealthy individuals
• funding for clean water programs slashed

I try not to view government spending as zero-sum because there's no saying that not spending money on X means that money automatically gets spent on Y. But the government's priorities could not be more clear: its citizens (and common citizens of the world) are not of any concern.

Rand Paul also voted against it so I think that there's more to it than a simple oversight of the funds going to Ukraine. I haven't read the text of what they voted on though.
