Health concerns plague ageing Congress members returning to Capitol Hill

Republicans Mitch McConnell and Steve Scalise join others in increased scrutiny over recent health issues

Lawmakers are returning to Capitol Hill as they race to reach a short-term funding deal by the end of the month to keep federal agencies open and avert a government shutdown. But worries about the health of two top Republicans loom over the high-stakes talks as politicians' age has become a growing concern.

Speaking to reporters last week in Kentucky, Mitch McConnell, the 81-year-old Senate Republican leader, appeared to freeze for 30 seconds after calling the possibility of a shutdown a pretty big mess". The incident raised questions about his health and mirrored an earlier incident where he suddenly paused for several seconds while speaking to reporters at the US Capitol.
