                        poses an imminent and substantial danger to 
                        life or limb;
            ``(2) the term `knowingly', as related to an element of an 
        offense, means--
                    ``(A) if the element involves the nature of the 
                conduct of a person or the attendant circumstances,

                is of that nature or that such circumstances exist; and
                    ``(B) if the element involves a result of the 
                conduct of a person, that the person is aware that it 
                is practically certain that the conduct of the person 
                will cause such a result;

        intentionally, maliciously, knowingly, recklessly, wantonly, 
        negligently, or with reason to believe, or any other word or

        offense, means that the person acted with knowledge that the 
        person's conduct was unlawful.
    ``(b) Default Requirement.--Except as provided in subsections (c) 
and (d), a covered offense shall be construed to require the Government 
to prove beyond a reasonable doubt that the defendant acted--
            ``(1) with the state of mind specified in the text of the 
        covered offense for each element for which the text specifies a 
        state of mind; and
            ``(2) willfully, with respect to any element for which the 
        text of the covered offense does not specify a state of mind.
    ``(c) Failure To Distinguish Among Elements.--Except as provided in 
subsection (d), if the text of a covered offense specifies the state of 
mind required for commission of the covered offense without specifying 
the elements of the covered offense to which the state of mind applies, 
the state of mind specified shall apply to all elements of the covered 
offense, unless a contrary purpose plainly appears.
    ``(d) Exceptions.--
            ``(1) In general.--Subsections (b)(2) and (c) shall not 
        apply with respect to--
                    ``(A) any element for which the text of the covered 
                offense makes clear that Congress affirmatively 
                intended not to require the Government to prove any 
                state of mind with respect to such element;
                    ``(B) any element of a covered offense, to the 
                extent that the element establishes--
                            ``(i) subject matter jurisdiction over the 
                        covered offense; or

                        covered offense; or
                    ``(C) any element of a covered offense, to the 
                extent that applying subsections (b)(2) and (c) to such 
                element would lessen the degree of mental culpability 
                that the Government is required to prove with respect 
                to that element under--
                            ``(i) precedent of the Supreme Court of the 
                        United States; or

                        any other Act of Congress, or any regulation.
            ``(2) Mere absence insufficient.--For purposes of paragraph 
        (1)(A), the mere absence of a specified state of mind for an 
        element of a covered offense in the text of the covered offense 
        shall not be construed to mean that Congress affirmatively 
        intended not to require the Government to prove any state of 
        mind with respect to that element.
    ``(e) Applicability.--This section shall apply with respect to a 
covered offense--
            ``(1) without regard to whether the provision or provisions 
        specifying the covered offense are enacted, promulgated, or 
        finalized before, on, or after the date of enactment of this 
        section; and
            ``(2) that occurred--

                                with the covered offense of any defense 
                                available according to law at the time 
                                the covered offense occurred;

                        in a prosecution for the covered offense before 
                        the date of enactment of this section;

                        a prosecution for the covered offense tried 
                        without a jury before the date of enactment of 
                        this section; or

                        following a plea of guilty or nolo contendere 
                        in a prosecution for the covered offense before 
                        the date of enactment of this section.
    ``(f) Subsequently Enacted Laws.--No law enacted after the date of 
enactment of this section shall be construed to repeal, modify the text 
or effect of, or supersede in whole or in part this section, unless 
such law specifically refers to this section and explicitly repeals, 
modifies the text or effect of, or supersedes in whole or in part this 
section.''.
    (b) Technical and Conforming Amendment.--The table of sections for 
chapter 1 of title 18, United States Code, is amended by adding at the 
end the following:

``28. State of mind when not otherwise specifically provided.''.
Mens Rea Reform Act of 2015 This bill amends the federal criminal code to establish a default intent (state of mind)standardfor a federal criminal offense, unless the provision of law that defines such offense specifically provides otherwise. A federal criminal offense conviction under the default standard requires proof beyond a reasonable doubtthat a defendant acted intentionally and willfully with respect to each element of the offense.If a state of mind is not specified for an element of the offense, it must be shown that the defendant acted willfully. A person who acts &quot;willfully&quot; does so with the knowledge that the conduct is unlawful. The bill sets forth certain exceptions where the default standard shall not apply. Additionally, the bill requires that when a provision of lawidentifies an intentstandard but does not specify which elements of the offense the standard applies to, the identified standard must apply to all elements of the offense.
