GOP lawmaker issues warning about unprecedented Chinese expansion.

GOP lawmaker Rep. Michael Waltz has warned that China is "on the march" and may make a move "the likes of which we have never seen in the world" in the next few years. He emphasized the importance of maintaining a strong defense budget to ensure national security and expressed concerns about jeopardizing it to reach a deal on the debt ceiling. President Biden's defense budget has been criticized by Republicans as insufficient amid rocky relations with U.S. adversaries. A bipartisan budget agreement was reached to avoid a debt default crisis, but concerns remain about the potential impact on national security.
