On Tuesday, Rep. Tim Murphy has introduced an updated version of his sweeping mental health reform legislation, seeking to allay some of the concerns of Democrats. The move has come a day before the bill was marked up in the House Energy and Commerce health subcommittee.

The measure was billed as the Republican response to the mass shooting in Newtown, Conn. Firstly introduced in 2013, it has been controversial and delayed for years, but has now started moving forward.

The bill has received some bipartisan support, among its supporters 43 of 154 cosponsors were Democrats, but Democrats on the Energy and Commerce committee have come up with objections to many core parts.

On Tuesday morning, the new bill was just shared with committee Democrats, and ranking member Rep. Frank Pallone (D-NJ) said that he was still left with reviewing the alterations, but can’t be in the favor of the bill in the form it had been earlier.

A most controversial part of the bill incentivizes has suggested the adoption of what is called Assisted Outpatient Treatment (AOT), where judges can order treatment for patients having serious mental illness.

Committee Democrats had given warning that the bill as written would have withdrawn federal funding from states that were not having AOT laws. The new version of the bill is seeking to make it clear that the funds will not be rescinded just the states that have the laws in place will get a 2% increase in funding.

Democrats still object to the incentive. In a letter earlier this month, 19 committee Democrats wrote, “The use of the court system and law enforcement to force individuals into care is a dramatic departure from how individuals, particularly those who pose no imminent threat to themselves or others, obtain health care services in this country”.
