NEW YORK (Reuters) – Police were investigating a suspected explosive device found in New York City on Thursday after a series of other package bombs were sent this week to current and former Democratic U.S. politicians, CNN and a prominent Democratic Party donor.

The New York Police Department said it was handling a suspicious package in Manhattan’s Tribeca neighborhood. A police source said the package was addressed to actor Robert De Niro, who has been critical of Republican U.S. President Donald Trump.

Following are the figures targeted:

FORMER U.S. SECRETARY OF STATE HILLARY CLINTON:

A suspicious package sent to Clinton, Trump’s Democratic rival in the 2016 presidential election, was found late Tuesday during an off-site mail screening, according to the Secret Service. Clinton said later her family was fine.

FORMER U.S. PRESIDENT BARACK OBAMA:

The Secret Service uncovered a suspected explosive device sent to Obama’s residence in the Kalorama district of Washington, D.C., early on Wednesday during a screening. Officials said Obama was not at risk.

CNN, FORMER CIA DIRECTOR JOHN BRENNAN:

New York City Police evacuated the Time Warner Building Wednesday after a suspicious package was found in the CNN mail room. The package was addressed to Brennan, who is an outspoken Trump critic and a periodic contributor to the network.

BILLIONAIRE FINANCIER GEORGE SOROS

A small bomb was found on Monday in a mailbox outside a New York home of billionaire financier George Soros, one of the world’s biggest donors to liberal groups and causes. Soros, who was not at the property, is a hated figure among some right-wing activists in the United States and Eastern Europe.

U.S. CONGRESSWOMAN FROM FLORIDA DEBBIE WASSERMAN SCHULTZ AND FORMER ATTORNEY GENERAL ERIC HOLDER:

The building housing the Florida office of Wasserman Schultz, former chairwoman of the Democratic National Committee, was evacuated after a suspicious package was found, according to media reports. The package was addressed to Holder but Wasserman Schultz was named on the return address.

U.S. CONGRESSWOMAN FROM CALIFORNIA MAXINE WATERS:

The FBI said on Wednesday it was investigating two packages addressed to Waters, who had also said Capitol Police told her that her Washington office was a target.

ACTOR ROBERT DE NIRO

A suspicious package similar to those sent to Clinton, Obama and others had been addressed to Robert De Niro at property he owns in Manhattan’s Tribeca neighborhood, according to a New York Police Department source. De Niro has been critical of Trump, who in turn has criticized the actor.
