House Republicans holding a field hearing Monday in downtown Manhattan on crime in New York City are expected to wade into the debate over bail and criminal justice reform measures at the state level that some in law enforcement say are making the job of policing the city harder instead of easier. 

After President Trump was indicted last month by the Manhattan district attorney, Alvin Bragg, the House Judiciary Committee announced that it would hold the hearing to examine Mr. Bragg’s track record in keeping criminals off the streets as he targets Mr. Trump. The committee is headed by an Ohio Republican, James Comer, who is one of Mr. Trump’s most vociferous supporters on Capitol Hill.
