WASHINGTON — The House intelligence committee has subpoenaed President Donald Trump's personal attorney, Michael Cohen, as part of its ongoing investigation into Russia's election meddling and contacts with the Trump campaign, according to a congressional aide.

The aide spoke on condition of anonymity in order to discuss internal committee matters.

Cohen, a longtime attorney for the Trump Organization, remains a personal lawyer for Trump. He served as a cable television surrogate for the Republican during the presidential campaign.

The subpoena for Cohen comes as the congressional investigations into ties between the Trump campaign and Russia advance beyond formal requests for information from Trump associates. The president's first national security adviser, Michael Flynn, has also received subpoenas from the Senate panel regarding his Russian contacts and his business records. The House intelligence committee has also subpoenaed Flynn, the congressional aide said.

"I declined the invitation to participate as the request was poorly phrased, overly broad and not capable of being answered," Cohen told The Associated Press. "I find it irresponsible and improper that the request sent to me was leaked by those working on the committee."

Cohen told ABC News Tuesday that he had been asked by both the House and Senate intelligence committees to provide information and testimony about contacts he had with Russian officials.

Russian President Vladimir Putin said the allegations of Moscow meddling in the U.S. presidential election are "fiction" invented by the Democrats in order to explain their loss. In an interview with French newspaper Le Figaro, Putin reaffirmed his strong denial of Russian involvement in the hacking of Democratic emails. The interview was recorded during Putin's Monday trip to Paris and released Tuesday.

Trump made a similar claim in a tweet early Tuesday: "Russian officials must be laughing at the U.S. & how a lame excuse for why the Dems lost the election has taken over the Fake News."

Cohen's ties with Russian interests came up in February when the New York Times reported that Cohen helped to broker a Ukraine peace plan that would call for Russian troops to withdraw from Ukraine and a referendum to let Ukrainians decide whether the part of the country seized by Russian in 2014 should be leased to Moscow. The Russian government denied knowing anything about such a plan.

The Times reported that the peace plan was the work of Felix Sater, a business associate who has helped Trump try to find business in Russia, and Cohen.

Cohen was a fierce defender of Trump during the campaign, often haranguing probing reporters and famously challenging a CNN reporter live on-air to name the specific polls that showed then-candidate Trump behind his rival, Hillary Clinton.

In the early 2000s, he formed his own firm working on a range of legal matters, including malpractice cases, business law and work on an ethanol business in Ukraine. Cohen also owned and operated a handful of taxi medallions, managing a fleet of cabs in New York.

Cohen's business associates in the taxi enterprise included a number of men from the former Soviet Union, including his Ukrainian-born father-in-law.

Cohen has made his own unsuccessful attempts at public office, losing a city council race and briefly running for state assembly in New York.
