WASHINGTON (AP) — A bill that enhances health care and disability benefits for millions of veterans exposed to toxic burn pits has hit a snag in the Senate. Veterans groups are denouncing the delay, saying servicemembers exposed to the burn pits in Iraq and Afghanistan have waited long enough for care. Republicans largely support the measure but blocked it last week, saying it could lead to an explosion of spending unrelated to veterans. It’s unclear how the delay will be resolved, though a deal could be reached this week. President Joe Biden has said he will sign the bill once it clears Congress.
