Joe Kennedy III is a congressman from Massachusetts who is quickly rising the ranks of the Democratic Party, but he's come under fire for his views against marijuana legalization. But Kennedy continues to hold steadfast, as shown in a recent television appearance.

Kennedy went on Jimmy Kimmel Live last night to discuss his famous family (he's Robert F. Kennedy's grandson and JFK's great-nephew), Donald Trump and other political issues. Near the end of the interview, he and Kimmel began discussing healthcare when the issue of marijuana legalization came up. Kennedy continued to defend his anti-marijuana views. He basically said he was concerned about how legalization would affect adolescents and people with addictions, but that was about it. Take a look at the interview:

Of course, studies have shown that legalization has not led to more teenagers using marijuana, and recent studies show that marijuana legalization actually has helped reduce the number of people abusing opioids, so it seems that neither of his concerns are particularly valid.

Kennedy's ascension in the Democratic Party has received criticism from many progressives. Not only does he not support marijuana legalization, but he's also not supported single-payer universal healthcare proposals that have been supported by a large number of Democrats.

To his credit, Kennedy did briefly criticize Jeff Sessions and the Trump administration's handling of marijuana legalization in the Kimmel interview, although it's not entirely clear how he wishes they would actually respond on the issue.

Considering his age and family name, you can be sure that Kennedy will be factor in the Democratic Party for years to come. Hopefully he evolves on some of these issues.
