Harris calls for end to Senate filibuster to restore US abortion rights

Democratic nominee focuses campaign on reproductive freedom' and says 60-vote threshold should be abolished

Kamala Harris has called for an end to the Senate filibuster to make good on her pledge to restore the right to abortion through legislation.

The US vice-president, herself a former senator, told a radio station in Wisconsin that eliminating the filibuster - which sets a 60-vote threshold in the 100-seat upper chamber of the US Congress - would be necessary to codify the rights that were enshrined in Roe v Wade, the 1973 supreme court ruling that upheld the right to legal abortion throughout the US until it was overturned by a ruling two years ago.
